Have you ever wondered why ceramics are hard and brittle while metals tend to be ductile?  Why some materials conduct heat or electricity while others are insulators?  Why adding just a small amount of carbon to iron results in an alloy that is so much stronger than the base metal?  In this course, you will learn how a material’s properties are determined by the microstructure of the material, which is in turn determined by composition and the processing that the material has undergone.
This is the second of three Coursera courses that mirror the Introduction to Materials Science class that is taken by most engineering undergrads at Georgia Tech.  The aim of the course is to help students better understand the engineering materials that are used in the world around them.  This first section covers the fundamentals of materials science including atomic structure and bonding, crystal structure, atomic and microscopic defects, and noncrystalline materials such as glasses, rubbers, and polymers.

Phase Diagrams and Phase Equilibria

This course picks up with an overview of basic thermodynamics and kinetics as they pertain to the processing of crystalline materials. The first module deals with phase diagrams - charts that tell us how a material will behave given a certain set of variables such as temperature, pressure, and composition. You will learn how to interpret common and complex phase diagrams and how to extract useful information from them.

Kinetics of Structural Transformations

If thermodynamics, which we covered in the previous module, tells us how a material wants to change, then kinetics tells us how and how quickly that transformation occurs. This module starts by explaining the driving force for phase transformations. We will cover the nucleation and growth of precipitates, solidification, and sintering. Finally, there are a number of lessons which apply all that has been covered in the course to understanding carbon steels.

TOP REVIEWS FROM MATERIAL PROCESSING

by JCMar 1, 2021

A complete guide to phase transformation and underlying principles. Such a wonderful course for 'materialists'. Thanks for your crisp delivery.

by APMay 28, 2020

the course is well organised and very descriptive. prof. Sanders has explained the concepts very clearly with the help of graphs and theoretical calculations.

by SRApr 11, 2020

I Great thank to Professor Thomas H. Sanders, Jr. for providing valuable information . I joyed a lot on Material Processing course and i learnt new information.

by MJMay 10, 2020

I wonder I'll ever find a course as organised and resourceful as this one. One of the best courses on the web by one of the best universities in the globe. Thank you G.Tech.

Frequently Asked Questions

When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
