1.	The mechanical strength of the metal decreases due to the strain hardening of the metal.(a) True(b) FalseThe question was posed to me in an international level competition.I'd like to ask this question from Behaviour in Metal Forming in portion Forming Process of Casting-Forming-Welding II
Answer» RIGHT choice is (B) False To elaborate: At room temperature, the stress-strain curve of most of the materials indicates the deformation of metal. When deformation occurs, the mechanical strength increases DUE to the strain HARDENING. The stress NEEDED for continuing the deformation should be increased to match this increase in strength.
