奥－贝球铁断裂与疲劳研究的新近进展

摘要

奥－贝球铁具有很强的强度、塑性、韧性、疲劳强度和耐磨性等综合性能，应用日益广泛，已成为一种重要的工程材料。近年来对其断裂与疲劳的研究发展很快，得到不断的深入，本文详细介绍了其新近进展。%Austempered ductile irons (ADI) exhibit excellent combination of strength, ductility,toughness, fatigue strength and wear resistance. They have been successfully used in many fields and become an important engineering material. The fracture and fatigue of ADI have been investigated extensively in the recent years. The recent developments on the mechanisms of fracture and fatigue in ADI are reviewed in this paper.
