Lecture 7

Question 1

What are the types of stress and strain?

Answer 1

tension, compression, shear, and torsion

Question 2

Can you prepare a substitutional alloy of Co / Cu 50%/50%? Yes/No. Why?

Answer 2

No, a 50%/50% substitutional alloy of Co and Cu cannot be easily prepared because their atomic sizes differ significantly, and they have different crystal structures (hcp for Co and fcc for Cu), making it difficult to form a stable alloy.
