i need manual solution of diffusion in solid(shewmon) if
you have plz send for me. tank you
my email : email@example.com
where do i get previous question papers of metallurgy?
what is No.1 Laathing Scrap Bundle ( Mill Scrap )
How to melt the solidified copper accretions in copper
scrap melting furnace?
what are different grades of mild steel available for making
machine structure (housing)
Why are the superalloys sometimes subjected to secondary
What is chemical composition and mechanical properties of
IS 2004,Gr-3 and IS 305 AB-2?
I currently use 17-7 PH stainless which is hardened to
condition CH after forming. raw matl is .1.75"X .12"
X .008". Its main usage after hardening is silicon wafer
retainer where it's contantly cycled up and down to putin
and remove wafer after 40-60 sec process at 400C temp. At
this high temperature this part seemed to deform after a a
couple of hundred wafer which is what it was designed for
in the first place. THere is a proposal to go to a
different material to increase lifeline of this part. My
question is..... can 321 SST be a plugin replacement. I
know this has a higher temp rating but how about its
forming characteristics, will it have spring properties,
and wont become brittle after prolonged exposure to 400C.
i need some information about prevent eutectic carbide
network(as cast) formation in 12% cr steel casting by
another alloying element(my analays: c=1.2-1.4 cr=11-13
mo=0.2-0.4 ni=0.2-0.4 )or break network carbid after
formation in solidification by heat tretment
please help me

For the same part, it is possible to Specify the two
different type of Hardness with same scall(EX-Quenching and
tempering==>450 to 500HV30 & Hardening and Austempering 330-
white rust formation over zinc plated and passivated
fasteners during CED coating. WHY?
sir please send me previous question papers on metallurgy at
email@example.com .....thank you
i m going to give an interview for iocl on 5th aug . pls
tell me what questions can be answered from metallurgical
any input on how to spec out(if possible) a larger grain
structure(3/8" or larger) on a Al 6061 forging material.
What is the difference between DI pipes, Cast Iron pipes, LA
Pipes, SW pipes, SWR Pipes, RCC hume pipe, RCC spun pipe ?
What are their IS codes and applications ?
