| Abstract: | In this paper, the efffects of Re modification on the microslructure, mechanical properties and abrasion resistance of Cr12 white cast iron arc invcstigated. The results shown that finer austenite dcndrites arc obtained by modification and carbides arc fine, isolated broken rods, the impact toughness is increased by 36.2% and abrasion resistance by 37.8%. |
