Summary

Researchers have discovered that the properties of high alloy tool steels can be improved by cryogenic cooling to -70 deg C before tempering at 210 deg C, and improved further by a double cycle of cooling and tempering. The reason lies in the cryogenic effect of increasing the quantity of the martensite supersaturated components in the alloying elements and the carbon. This leads to a redistribution of the alloying elements between the matrix and carbides during tempering. This increases hardness and wear resistance. D.W.H.
