Question

Materials like lead (Pb) and tin (Sn) can be hot worked at room temperature.

(a) True

(b) False

I have been asked this question in homework.

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

Answer 1

Correct choice is (a) True

For explanation I would say: Hot working or hot forming of materials is normally performed at the temperature above than its re-crystallization temperature, but for materials like lead (Pb) and tin (Sn), the hot working can be done at room temperature because these materials possess very low crystallization temperature.
