A NIMS research team fabricated heat-resistant steel test specimens using laser powder bed fusion (LPBF)—a form of metal 3D ...

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

The micrographs below show the effect of annealing at different temperatures on a sample of Fe - 0.7 wt % C steel in which martensite has been formed by quenching. Because of the low carbon content ...

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 ...

A team of researchers from Japan’s National Institute for Materials Science (NIMS) has made a breakthrough in metal 3D ...
