Question

Forming is a process that changes the shape of the metal by changing its phase.

(a) True

(b) False

I had been asked this question in an interview for job.

The query is from Metal Forming Processes topic in division Forming Process of Casting-Forming-Welding II

Answer 1

Correct answer is (b) False

The best I can explain: Forming is basically a term that covers many manufacturing processes. In the metal forming process, the shape of the material or metal is changed by performing an operation like hammering, squeezing, bending, pulling etc. without changing its phase. The raw materials used in the forming process remained in a single solid phase.
