Question

Malleability increases with temperature while ductility decreases with temperature.

(a) True

(b) False

I faced this question in my study session.

This problem is from the Stress Strain Diagrams & Mechanical Properties of Engineering Materials unit in Engineering Materials of Machine Design

Answer 1

Correct option is (a) True

To put it plainly: Malleability is the deformation under compressive load and hence with rise in temperature, the deformation increases and hence malleability increases.
