If the cooling rate is less than 35 C/s the final material will be pearlite - the thermodynamically stable low temperature material. At cooling rates faster than 140 C/s the transition is to a ...

TEM images revealing the nanoscale interactions between martensite laths in the solution-annealed state; (e) Visual representation of the synergistic effects between annealing twins and martensite ...

The micrographs below show the effect of annealing at different temperatures on a sample of Fe - 0.7 wt % C steel in which martensite has been formed by quenching. Because of the low carbon content ...
