摘要：
Hardenability is one of the basic properties determining the suitability of wear-resistant alloys for the production of castings, especially thick-walled ones. In this work an investigation was made of the influence of carbon and chromium on the hardenability of cast irons. In alloying of cast irons with chromium alone it is impossible to obtain a high hardenability providing a martensitic-austenitic structure in hardening of castings more than 30 mm thick. To provide high hardenability chromium irons must be alloyed with elements increasing the stability of austenite, such as manganese.
