THE lattice parameters of martensite and austenite in steels (carbon content varying from 0.57 to 1.74 per cent) have been extensively studied; but considerable discrepancies exist in the values ...

1). Preventing the substitutional solute, manganese, from partitioning between the ferrite and the austenite adds a substantial amount of energy but the greatest stored energy increase comes from the ...

Between 35 and 140 C/s the system at room temperature is a mixture of these two materials. The microstructure of martensite in austenite is shown in the micrograph. The black grains are the ...

The micrographs below show the effect of lowest temperature on the formation of martensite in an Fe -1.8 wt % C alloy. The material is initially heated above 727 C and converted to a homogeneous ...
