In regard to non wear resistance of the white ironshot in the practical application process, alloy ironshot have been produced by means of adding alloying element and proper heat treatment.
Three methods of surface self-nanocrystallization for iron and steel are ultrasonic shot peening, high energy shot peening and surface mechanical attrition treatment.
实现钢铁材料表面自身纳米晶化的主要方法有超声喷丸、高能喷丸和机械研磨处理等。

Based on the experiments of shot peening to some specimens, the paper makes an approach to strengthening mechanism and fatigue resistance technology for nodular cast iron.
