Question

In cold working, larger deformation can be obtained more rapidly than that obtained by the hot working.

(a) True

(b) False

I had been asked this question by my school teacher while I was bunking the class.

The doubt is from Advantage and Disadvantage of Hot and Cold Forming topic in chapter Types of Die & Metal Forming Processes of Casting-Forming-Welding II

Answer 1

Correct answer is (b) False

The best explanation: The mechanical properties, elongation and izod values are enhanced in the hot working of materials. In hot working, the other properties like directional properties and fibre are also produced in the material which helps in achieving the larger deformation more rapidly than that obtained by the cold working, as the material is present in the plastic state.
