The interstitial alloy between carbon and iron has a complex phase diagram. A compound ... at 1538 C it returns to body-centered cubic. Low carbon steel alloys have a composition close to the ...

FOR the sake of simplicity, we shall consider the case of an eutectoid steel ; if the steel is cooled slowly from the austenitic region, a well-known pearlite structure is formed in crossing the A ...

The diagrams show the effect of changing ... The hypoeutectoid steel is the most ductile and the ductility has decreased by a factor of three for the eutectoid alloy. In hyper-eutectoid alloys the ...
