Case hardening of non-ferrous materials can be done easily as compared to that of ferrous materials.(a) True(b) FalseI got this question in an interview for job.The question is from Method of Heat Treatment in portion Heat treatment of Metals and Alloys of Casting-Forming-Welding II

Answer»

Correct option is (b) False

The best explanation: In general, all the heat treatment processes are SIMILAR as they all include heating and cooling of metals. The heat treatment of ferrous MATERIALS normally includes processes LIKE annealing, normalizing, HARDENING, or tempering. But for nonferrous metals, tempering, normalizing or case hardening cannot be DONE, they only goes through an annealing process.
