High-temperature austenite, an FCC structure, has enough space for carbon atoms to squeeze in between the iron atoms. Iron atoms keep their place on the lattice while carbon atoms become ...

The austenite crystals undergo a transformation involving the shearing of atom planes over each other. Martensite does not appear on the phase diagram (figure 1), as it is not an equilibrium phase.

The retained austenite in the leading edge analysis area is generally randomly distributed, whereas the trailing edge area shows a more segregated distribution, with the lower region having more ...

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, ...

In a significant leap for advanced high-performance steel, a research team from Zhejiang University have engineered a novel Fe-Ni-Al-Ti-C alloy that combines exceptional strength with remarkable ...

While it cools through this zone Fe 3 C is deposited on the austenite grain boundaries and the austenite composition moves to the eutectoid value. When the alloy reaches the eutectoid temperature the ...
