Sir, please add me to your fan followers list. Never had I ever enjoyed learning material science as I did after visiting your lecture series. Your explanation is really covering every nuance, like why >2% carbon is called cast iron (because melting point decreases & hence it is beneficial to use in casting). Sir, maybe I would run out of words to admire your explanation. Just to let you know, (without any intention to offend anybody), I started your lecture series after going through IIT Roorkee & IIT Bombay lectures on Phase diagrams. Your lectures & your explanation is just beyond comparison. Thank you for your efforts!

@rajeshprasad1015 жыл бұрын
I am trying to make a distinction between crystal and lattice. As I have explained elsewhere, Crystal=lattice +Motif. In my lectures I reserve FCC for lattice. Thus calling austenite FCC gives only a partial information about its crystal structure. Diamond and NaCl also have FCC lattice but have very different motif. Diamond has two atoms of the same kind as its motif whereas NaCl has two atoms of different kinds as its motif. Motif is CCP is different from both of these. Its a single atom motif. Thus CCP is a better description of the crystal structure of austenite than FCC.

@debbyblaine37284 жыл бұрын
As FCC is close-packed it can also be called CCP. FCC (face centered cubic) describes the unit cell (atom in the centre of each face and at the corners of the cube) - CCP (cubic close packed) describes the packing on the [111] plane of the FCC structure.

Austenite is the name of the phase. Gamma is the Greek symbol for the phase. CCP (Cubic close-packed) is the crystal structure.

@@engineer.paulmusyoka Calling it CCP is preferred to FCC. CPP means FCC lattice with single-atom motif. There are other crystals also which have FCC lattice, e.g.diamond. But the diamond is FCC lattice with two atom motif. In other words FCC only give the lattice whereas CCP gives both the lattice (FCC) as well as the motif (one atom) which is a more complete description of the crystal structure.

Sir What is upper critical temperature and lower critical temperature and what is the significance of these temp What are the values of the above temperatures
@introductiontomaterialsscience Жыл бұрын
the lower critical temperature is the eutectoid temperature. It is 725 C for plain C steels. Below this the steel has ferrite and cementite phases in its microstructure. On heating above this temperature transformation to austenite begins. At the upper critical transformation transformation to austenite completes and one has 100% austenite. For hypoeutectoid steels, the upper critical temperature varies between 910 C and 725 C (temperature of the gamma/ gamma+alpha boundary). For hypereutectoid steel it is the tempearture corresponding to gamma/gamma+cementite boundary.

why the 0.8 carbon is not the lowest melting point in the whole alloy system???
@introductiontomaterialsscience4 жыл бұрын
The composition 0.8 wt%C is the eutecTOID composition. Eutectoid reaction is completely solid-state reaction, there is lo liquid involved. Thus it does not correspond to the lowest melting temperature. But it does correspond to the lowest temperature at which ferrite+Fe3C transform completely to austenite. The eutecTIC composition corresponds to the lowest melting point. It is 4.3% C.

Sir, I have a question * How actually do we control the carbon percentage in iron, Is there a process?(like we have cyaniding carburizing, but those are limited to surface) * If yes then what are they if not then is it means that once we have a given steel with a given percentage of carbon, there is nothing we could do to change the composition, like you said we don't meet steel.

@introductiontomaterialsscience4 жыл бұрын
At one level, you can call it a composite. Ferrite is soft and ductile. Cementite is hard and brittle. Pearlite, a two-phase mixture of ferrite and cementite, can be considered an in-situ composite. The adjective 'in-situ" is to indicate that we did not separately make ferrite and cementite and then mixed them. The mixture was created internally during the decomposition of austenite on cooling. This is the reals difference between pearlite and a composite like GFRP (Glass Fibre Reinforced Plastic). Here, glass fibres and plastic are prepared separately and then combined to give the composite.

In Fe-Fe3C phase diagram why we don't have beta phase instead we are having gama and delta phases
@introductiontomaterialsscience4 жыл бұрын
This is a good question. Alpha iron is ferromagnetic. It transforms into a paramagnetic form above the Curie temperature of 770 C. This paramagnetic form was originally called the Beta iron. Although the magnetic state changes, the crystal structure of both alpha and beta iron is the same: bcc. So later, this classification was discontinued and beta iron was absorbed in alpha iron to indicate that there is no change in the crystal structure.
