At cooling rates faster than 140 C/s the transition is to a metastable material known as martensite. Between 35 and 140 C/s the system at room temperature is a mixture of these two materials. The ...

Unlike the tempered martensitic microstructure formed in conventionally heat-treated steel, LPBF-produced steel develops a high-temperature δ-ferrite phase-based microstructure due to its ...

Sustainable lightweight design through microstructure engineering The resulting nano-structured porous martensitic alloys are lighter and stronger, thanks to precise microstructure control from ...
