Abstract

Samples of spray formed AISI M2 high-speed steel were hot rolled at 50% and 72% reduction rates. The hot rolling was done at 1150 °C with sample reheating between steps. The samples were characterised by optical microscopy, scanning electron microscopy and x-ray diffraction. The obtained results were compared with commercial and as fabricated samples. The results are presented and discussed in terms of microstructure refinement, size and carbides distribution.
