Yeah, I was reading about these topics only from last Saturday. Please head to my advice, this is the wrong way of spending your weekend. So basically there is a lot to study, but everything is quite easy to understand. Video tutorials can be of great help in this issue, but alas, I couldn't surf for the same till now. I shall update the same here at the earliest.
What all needs to be covered:
- What are line defects, what are dislocations? ( both are same basically )
- Types of line defects viz screw dislocation & edge dislocation.
- How to find out the burgers vector for a given defect. What is burgers circuit, how to find out the direction of burgers vector. What is Burgers Vector?
- What are various types of surface defects?
- Study about grain boundary and interface, tilt boundary, twinning, stacking faults & such.
Note:
- Twinning is important concept as the same is asked many many times in the old question papers.
- For simple definitions of defects and classification please refer to material science by RS Khurmi & RS Sedha
- For brief and clear cut explanation please refer to the study material provided by AMIE
Resources:
- A good pdf which helps to visualize the dislocations is here
- A good image to help visualize point defects is here
- Another point defect explanation here
Don't forget to grab a copy of Material Science and Engineering book, which is essential for preparing for AMIE, Material Science.
with warm regards
