摘要：

Laboratory abrasive wear testing has been carried out on two austempered commercial spheroidal cast irons and compared with the results of similar tests on a range of abrasion-resistant carbon steels. All the austempered irons were found to have better abrasion resistance than proprietary abrasion-resistant steels. These austempered irons derive their outstanding properties from the morphology of the dual-phase ferritic-austenitic matrix coupled to the high work-hardening characteristics brought about by the stress-induced austenite-to-martensite transformation during abrasion. The influence of structure and mechanically induced transformation has been studied as a function of austempering temperature and time.
