Structure and properties of powder austenitic die steels

Possibilities are considered for using powder metallurgy in order to prepare effective austenitic die steels exhibiting high hardness and heat resistance (at temperatures not less than 850 °C). It is shown that in strength properties the material developed are as good as the best austenitic steels used as die tools, and in the level of heat resistance and hardness at room temperature they a considerably better. __________ Translated from Poroshkovaya Metallurgiya, Nos. 7–8(450), pp. 26–30, July–August, 2006.
