Finally...after almost a decade I understood what is pearlite😭

Won't there be any grain or grain boundary eutectoid microstructure? If yes, then will each grain have two phases present in it?

How can we calculate the % of gamma above eutectiod temperature in a 0.4% carbon steel?????

Which will form first from austinite - alpha or Fe3C?
@introductiontomaterialsscience4 жыл бұрын
Tricky question. Don't know :-(
@rafshantik3 жыл бұрын
I guess Fe3C will nucleate first. At 723 degree C, carbon diffusion is faster than Fe which helps carbon to cluster around Austenite GB, and if it's 25 atom percent, Fe3C will form.

How can we use a eutectoid phase diagram from a practical point of view?
@introductiontomaterialsscience3 жыл бұрын
Well, Fe-C diagram is the best practical example of eutectoid phase diagram. All heat treatment of steels depends essentially on controlling the eutectoid reaction.

Sir, above 725 degrees Celsius it is Gamma austenite right sir , it is not steel .?? Steel is only below 725 centigrade and at 0.8 it is eutectoid steel. So how come above above 725 at 0.8 composition it is eutectoid steel?
@k.h.vsandhya54933 жыл бұрын
So, is it like no matter what is the temperature composition less than 2 is steel alloys and greater than 2 is cast iron ?? Sir
@introductiontomaterialsscience3 жыл бұрын
Irrespective of temperature and microstructure we will call an alloy of Fe and C containing 0.8% C as eutectoid steel. Similarly for hypo and hypereutectoid steels.

i dont know why , my lecturers havent got these skills of teaching!!
@muralidharan10893 жыл бұрын
Sir I have 2 doubts 1) Eutectoid steels have structure of Pearlite alone or phases of ferrite and Cementite. 2) Hypo eutectoid steels have structure of Pearlite alone or phases of ferrite and pearlite. Which is correct sir.
@introductiontomaterialsscience3 жыл бұрын
Pearlite itself is a mixture of ferrite and cementite. Eutectoid steel will give only pearlite. Hypoeutectoid steel will have both pearlite and some ferrite, called proeutectoid ferrite, which is not part of the mixture.

In eutecoid reaction composition of carbon is not balnced

Could you please explain?
@anasalazazmeh57495 жыл бұрын
yeah .. how the eutectoid start at 0.8 wt% of carbon after that i get 0.02wt% c for alpha and 6.7 wt% c for fe3c .. the total carbon in the composition is 6.72 wt%c when the reactoin start at 0.8 wt% c i dont understand that ..from where the exceed carbon come ?..please explain ?
@suwarnaca95954 жыл бұрын
@@anasalazazmeh5749 Hey I think u have misunderstood. The carbon is conserved. see the fe3c by percentage will be less in the total sum and alpha will be more it is not 50% alpha 50% fe3c
