Abstract:

TS700 is a new precipitation hardening steel with high temperature resistance and excellent hot hardness developed for additive manufacturing of aluminium die casting tooling.TS700 parts were produced by L-PBF on a plate made in H11 tool steel treated at 45HRC. The interface between TS700 and H11 is investigated, as well as the microstructure evolution versus energy density (for different laser powers and scan speeds). The evolution of the microstructure with subsequent heat treatments is presented as well as some mechanical properties associated to the different microstructures obtained.
