Based on the cutting and polishing comparison experiments, the machinability and polishing performance of 1CrMn2MoVTiB non-quenched and tempered plastic mould steel were studied. The cutting comparison experiment showed that the plastic mould steel that had developed recently was better than P20 both in surface roughness and cutter wear; and the polishing experiment indicated that the surface roughness of the two plastic mould steels reached uniformity under the conditions that TriDent polishing fabrics and W0.5 polishing compound were adopted.

The aging hardened plastic mould steel 10Ni3MnCuAl after aging at 510 °C is investigated by scanning electron microscope (SEM), transmission electronic microscope (TEM) and three dimensional atom probe (3DAP). The results show that its microstructure is granular bainite after soluted. Its aging hardening is mainly due to the precipitation of a high density, nanoscale and fully coherent NiAl precipitation with the B2 structure for 4 h. Clusters associated precipitates from 3DAP results show that its aging hardening derives from multicomponent precipitate containing Fe, Ni, Al, Mn and Cu, and concentration of Fe decreases with the aging time, while that of Ni, Al, Mn and Cu are opposite, and the ratio between Ni and Al are roughly 1.
