Hi

This is RAMPRASAD… I am written the senior technical assistance ‘A’ on METALLURGY (Diploma Based exam on 9/03/2008). In exam most of the questions from the p.p.m, thermo dynamics, physical metallurgy, iron making, heat treatment, foundary technology, nonferrous. Less questions from fuels &refractory, steel making, welding, material testing, mechanical metallurgy.

I am writing some questions (I am not writing total questions) and answers (only some ans). Questions are asked only fundamentals. I think exam is very easy for fresher candates.
