OK introduction to material properties, but not rigorous (leaves out definitions, motivation and conclusions/consequences) and skips some things that come up on the quizzes. No worked examples.

Helped me recall an overview image of the course I took in my 1st year in mechanical engineering.

This course is not terrible, I learned a few things, but it is poorly designed.

Some things are explained as if to people who aren't familiar with the concepts at all, while others are explained as if to people who must already know a lot about the concepts. I often felt lost. The "quizzes" did not help, you could do well on them without actually understanding things (I remember one multiple-choice question where the options were something like (a) "Arrhenius's first law", (b) "Arrhenius's second law", (c) "Arrhenius's third law", and you didn't even have to look at the question or know what the law was to know the answer because only one of Arrhenius's laws had been mentioned in the course at all).

There are two types of videos in this course. In one type, the professor is in a lab or kitchen or classroom or something and is physically demonstrating things. These videos are useful and mostly understandable. The other type of videos are lecture-style things that appear to have literally been sliced out of some other more thorough set of videos - sometimes the professor refers back to "earlier" parts of the lecture that we haven't actually seen before. Concepts and variables are often introduced without even mentioning what they refer to.

Great course to review the topic of materials. I am currently working as a mechanical engineer and it has helped me to refresh the fundamental concepts covered during my degree. The material is presented in a clear way and I think this is a good approach to the subject.

Excellent course to get a quick refresh on this subject.

A short course, but I did come away with a better understanding of how materials behave at a molecular/atomic level. I already had some experience with semiconductor physics and some of the basic chemistry ideas. The deformation curve helped me cement how/why torque specs are developed and used. The eutectic and eutectoid explanations were also very helpful.

Great course for refreshing your Materials Science knowledge and also for people trying to know if this is the right path of study for them....

Needs a lot more context! Why why why are we learning each topic. I love all the math and the depth, but just say why we are learning each thing first!

How about modeling each of the 10 things after a historical case study? Like the invention of carbonated steel, vulcanized rubber, or high temperature super conductors...? The historical case will put the abstract processes into context.

The general contents of the course are very satisfying. The connections between units (i.e. things) are very good and consecutive. Each topic has a connection with at least another one. Everything starts with Arrhenius and ends with Arrhenius. I appreciate Prof. James Shackelford for establishing such a connection throughout the course which makes whole subject fully understandable. However there were some numerical problems on some quiz of things (units). These numerical problems are so simple but there were not any example that shows the method how to interpret these problems to solve though. The trainee is supposed to solve these problems from the given equations. But it is sometimes hard to realize how to use the formula practically if one is not directly working on this specific subject. The other thing is about the semiconductor subject in where the n doped extrinsic semiconductors and the donor electrons with the energy level close to the conduction band are explained very good. Whereas there is no information about the p doped extrinsic sc's and acceptor holes with the energy level close to the valance band. Of course this course is about the material science and does not contain the electronics subject which is related with the electron flow under certain electric field. But I wish I saw the p-n junction with associated Fermi diagrams and how it shows the valve characteristics to the electrons under certain conditions of electric field. But anyway I got so many things that I need and I appreciate for these.

PLUS: The course was well-organized, and the organization structure was clear and easy to follow.

PLUS: The learning goals of the course were embedded in the organization, allowing me as a student to see exactly what main points I was intended to take away from the course.

DELTA: The course would have been more difficult to understand if I did not have background in Material Science. This is a good refresher and solidifier of content, but maybe wouldn't be as excellent a way to learn the content the first time.

DELTA: Some of the lessons (Week 5 in particular) left me with questions about some of the content covered that I needed to do external research on to fully understand (eutectic vs eutectoid being a salient example).

OVERALL: This course helped me refresh my Materials Science knowledge while solidifying general learning points about the topic that made the material more accessible and useful to me than it was previously.

This is a recap of the most important things taught in Materials lectures on an engineering course. It is quick, concise and highlights what should be kept in mind when working with different materials. The only new material for me was the last thing on semiconductors which I found very interesting.

The only thing that could be significantly improved is the section on alloy phases. It's is an important topic and I think more time could be spent on that subject to provide a more well rounded understanding of the topic. However 9/10 things done well and the other being a bit rushed is still 5 stars in my book.

An excellent short introduction to materials science for engineers. If you haven't already read Shackleford's textbook, this video lecture series would be an excellent primer.

If you have recently studied undergraduate materials science or engineering then you will not need this course as it doesn't have time to delve too deeply into the theory. However, if you are like me and a few years out of education, it's an excellent albeit brief recap of materials and failure modes. It's possible to binge at 2x speed and complete this series in a day.

yes this is a awesome course was designed to understand how materials engineering important and play a supportive or growing role in every field of engineering . now i things its to basic to understand materials now your next step will design a course which is discuss about the "materials science and the coming world" that's sound interesting and it is also aware the people why materials in to important.

my best wishes with you hope you done good things for the world through spreading educational awareness.

I honestly think this course was very useful and a good refreshment of my material science knowledge. Hence I gave it 5 stars. However, I was going to give it 4 due to the fact that I really did not understand the last 2 things : eutectoid ; martensite and austenite relationships (thing 9) and the semiconductor part (thing 10).

I still gave it 5 stars because I really do not want to blame the course for me not understanding.

Good course in general and I am glad I was able to complete it.

This course was very useful to remind me the basic concepts of Material Properties and there usage on in modern engineering applications. I learnt the real meaning of the concept “structure leads to properties". All this knowledge acquired will be applicable in my day to day job duties in the automobilistic sector, giving me more base during a technical discussion. I recommend this course for any Product Design Engineer.

Good course summarizing the basics and fundamentally important topics in Materials Science. I wish I had taken this earlier during my university days to have a better appreciation of Materials. Good professor, easy to understand. I do wish there was a little bit more hands-on/calculations involved so that it would be a little easier and a little more helpful in taking the theory and making it a little more practical.

Loved the intuitive, ultra-concise approach. Professor Shackelford balances real-world testing, applications, and history with a minimalist overview of the mathematics. His segments on atomic-level mechanics help the student gain sight-unseen intuition for the phenomena that inform the math. A concise and memorable way to get a cursory understanding of the important concepts. His book is great too.

Excellent intro to Materials Science. The course covers the fundamental concepts such as yield stress, tensile strength, ductility and toughness without getting too involved in complex formulas. I have a background in mechanical engineering and found this course to be a good review of materials course I took in University.

Thank you sir for teaching in such a different and unique way. The way you teach is indeed very unique and it always kept me attentive during your lecture. Now i have understand all those concepts in a more better way and i am certain that this will help me in my future carrier as a material engineer. Thank you Sir

Very interesting choice of topics. An interesting mix of new material and things I had learned differently in various other disciplines (physics, chemistry, geology). Good course but not recommended if you haven't done high school and university chemistry unless you are very brave!

It has been a good opportunity to refresh and reorganize items studied at university. Well clear lessons allowed me to understand every word, although subtitles were not always correct. I suggest this course to everyone who wants to refresh his knowledges in material science.

A MUST COURSE FOR BUDDING MATERIAL ENGINEERS/ MATERIAL SCIENTISTS!!

Professor Shackelford is so awesome!! The way he taught the course helped me grasp the fundamentals of material science better than that taught during my four year bachelor tenure in Material engineering.

Great class on materials and how crystal and atomic bonds lead to material properties. The chapter on semiconductors was new material for me and very valuable to introduce me to valence and conduction bands. The other material was good review for me as a Mech. Eng.

The explanation given in this course, even to the most confusing and commonly misconstrued of engineering phenomenons, is basic and self explanatory. I'd recommend this course to any engineer who's looking for a better introduction to material science!

This course was extremely helpful to me regarding the knowledge I gained. Moreover, I am very thankful that this course was provided to me under financial aid and I could avail such an experience which would not be possible otherwise.
