Hi, I am Rachit Jain. I am a Final Year Student in Mechanical Engineering, Thapar University. I make courses for GATE aspirants.

Rachit Jain

THIS COURSE IS ABOUT THE DEFECTS IN CRYSTAL AS WELL AS SOLIDIFICATION GROWTH

(Hindi) Physical Metallurgy- Iv Defects in Crystal, Solidification Growth

This course covers Important topics related to Material Science(module 1). About 30-40 % of the syllabus covers almost 90% of the question that comes in exam and rest 10 % questions are very rare and can be asked in exams like ESE.
