Lecture 1

Question 1

what is the difference between materials science and materials engineering?

Answer 1

materials science only deals with the relationship between the material’s structure and property. meanwhile, materials engineering deals with the interrelationship of the material’s structure, property and design that will give rise how these materials will perform in application.

Question 2

explain briefly the flow overview of materials science and engineering

Answer 2

first, we processed (processing) the material, which can lead to knowing its structure, then the properties and the performance of the material when applied
