Hi Friends
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.
EXAM PATTERN:
Technical questions -- 40 marks
Aptitude questions -- 10 marks
Exam paper total object type questions.
DURATION: 1 hr
1)pine oils are used in-----
ans: frothers
2)TTT diagram is also known as-----
a)s-curve b)c-curve c)isothermal transformation d)all

3)Hyper eutectoid-----
ans: perlite+cemtite
4)In austempring process-----formed

6)In nodular cast iron ----added
ans: mg
7)p+f=------
ans:c+2
8)line diffect-----
