1.	Cold rolling is a process of permanent deformation of material below its re-crystallization temperature.(a) True(b) FalseThe question was posed to me by my school teacher while I was bunking the class.My question is based upon Cold Rolling in division Mechanical Working of Metals of Casting-Forming-Welding II
Answer» Correct ANSWER is (a) True The best EXPLANATION: Cold ROLLING or working is a process of permanent or plastic deformation of materials below the re-crystallization temperature, and this process is generally performed at the room temperature. This process is widely used for producing products of better surface finish with superior dimensional CONTROL.
