for martensite formed in quenched steel, the carnon atoms are found in the interstitial places of the bcc iron unit, so create a lot of strain to the lattice, making it deform and form a tetragonal structure, this it what i get from some website
''All atoms shift in concert, and no...
alrite, thanks for the xplanation, here's just a year 12 stuff which i m stuck in:
ss steel is tough coz it undergoes tempering, i think it's becoz ususally tempered steel r produced from reheating quenched steel(which has a hard structure due to the rapid coolin time), and because in...
um.. what i mean is..
what's phy property make it suitable for this application
y is stainless steel used.
it must have something special to do wif it.. i know corrosion resistance is one.
well, i think hardness should count. and may be it got great wear resistance. in general, anything...
i need urgent help
can anyone suggest some link that clearly states the physical property needed for a stainless steel knife?
i desperately need it today.
thz
any help will be GREATLY appreciated
is tempering the correct heat treatment for automotive panel? coz I've seen different version of heat treatment.. some books said tempering, website said (key to steel) said case processing/ annealing (seldom quenching and tempering), actually which one is correct?
actually i'd prefer...
internal structure <-->property?!
can anyone suggest some link relating the internal structure of steel (like crystal arrangement such kind of thing) to their property like malleability, hardness etc.
it's hard to get information from search engine.
(it'd be better if it talks about the...
whao... thanks a lot for the links, they'r brilliant!
but, i have a little question
mild steel is one of low carbon steel which means not so strong when compared to high carbon one, why is mild steel used instead of high carbon steel?
well, i was thinking whether the mild steel is heat...
um.. actually, i want to talk about mild steel used in car bodies, because it has to be crash worthiness, so i think i better explain the shock absorbing property of that. is that related to the internal structure (the arrangment of the atoms) or the compositions that makes up mild steel?
URGENT! about iron and magnetism
can u explain briefly the magnetism of iron? i know that some iron ore--haematite and magnetite r called natural iron, but what contribute to the magnetic behaviour of iron?
and, what r the application of iron? all i could find from the internet only gives a...
