The stop-quenching solidification of steel R6M5, R6M5F3, R6M5K5 was studied. The furnace was a horizontal-type vacuum with a quenching tank provided with a thyristor system. The specimens were examined by optical and scanning electron microscopy and also by electron microprobe. The method of stop-quenching was found to increase the cooling rate for a fuller completion of the peritectic reaction, establish a connection between the peritectic and the eutectic reaction in high speed steels, and broaden the temperature range of peritic transformation under conditions of accelerated heat removal.
