Thanks a lot, I never quite understood what the diagram was actually used for

Hi great video, also what would you do if you were asked to figure out the amount of eutectoid cementite?

@siva-rk5oh 5 ай бұрын

Eutectoid cementite is basically the Fe3C present in pearlite. we can just get it by removing the pro eutectoid (which is cementite in this case) from the total cementite value we got

Great video, I have a question how do the microstructures look like if for example at 5wt%C it's cooled to 700°C

@TaylorSparks 10 ай бұрын

It depends on the processing history. Was it cooled slowly quickly rapidly? Was it held at a temperature at any point? Was it annealed? All of these things modify the microstructure. So asking how the microstructure looks at a certain composition and temperature the phase diagrams will only tell us the equilibrium phase fraction, but the processing steps will give us much more insight about the distribution of those phases which is often related to the properties of interest

Great video! For part c), is asking for the wt% of pearlite and cementite the same as asking for austenite and cementite?

@TaylorSparks 4 жыл бұрын

Good question. we know that after the material undergoes the eutectoid reaction all of the austinite is converted to a mixture of pearlite and cementite. This happens relatively quickly and so it forms the lamellar structure which we would call pearlite. It's possible to form proeutectoid phases though, such as proeutectoid ferrite or proeutectoid cement.
