For eutectoid steel:
b) Sketch the thermal history (i.e., path) and calculate the
final microstructure when the steel has the following heat
treatment sequence : i) instantaneously quenched from 850 C to 300
C, ii) held at 300 C for 1 hour, and iii) air cool to 20 C.
(Materials science)
Explain why adding Ti or Si can raise the eutectoid temperature
of steels? What is the impact of having higher eutectoid
temperature on using heat treatment to obtain Bainite? Use the CT
or TTT diagram to explain.
