KMU 396  - MATERIALS SCIENCE AND TECHNOLOGY-I

Spring Semester

 

INSTRUCTOR:

Dr. Selis ÖNEL|  selis@hacettepe.edu.tr
 

COURSE GOALS:

Students will learn about:

  • Material structure

  • How atomic and micro structure determines properties

  • How processing can change structure

This course will help to:
