preventing equilibrium phase formations and resulting in a hardened microstructure characterized by martensite. Sometimes, ...

SOME observations were made of the effect of heating rate on the martensite (M)→austenite (γ) reversion in a 300-grade 18 per cent nickel maraging steel. These are discussed here with reference ...

The joining of two steel plates (pearlite) by welding is shown in the top diagram together with temperatures in the weld zone and the regions of the two plates altered by the process. The lower ...
