The austenite grain growth in microalloyed steels is governed by thermally activated migration of grain boundaries, influenced by the presence of solutes and precipitates. At elevated temperatures, ...

Retained austenite plays a crucial role in determining the hardness, toughness, and strength of martensitic steel alloys. The quenching of these alloys forms a hard martensitic phase, but incomplete ...

The Dub classification applies equally well to the various morphologies of cementite formed at progressively lower transformation temperatures. The initial development of grain boundary allotriomorphs ...

Metalworkers and metallurgists have long appreciated the ability to tailor the performance characteristics of steel (an alloy of iron and carbon), including their strength, hardness, ductility and ...

TRIP steels have a microstructure consisting of at least five volume percent of retained austenite, which is embedded in a primary ferrite matrix. The microstructure also contains hard phases like ...

The eutectoid phase transition in the iron carbon system takes place at 727 C. The three components in equilibrium at this temperature are Austenite, g, with the composition Fe - 0.77 wt % C, Ferrite, ...
