硬脆材料塑性区域加工研究综述

硬脆材料具有良好的物理和力学特性,在航空航天和工业生产中得到广泛应用。但由于其高的硬度和脆性,使其加工过程变得非常困难。塑性域加工方法的提出是解决硬脆材料加工过程中产生的缺陷的一种有效方法,因此硬脆材料的塑性域和脆性域加工转换的临界条件获得广泛研究。从塑性域加工机理、塑性域加工模型、表面/亚表面损伤和塑性域加工的影响因素对国内外的研究现状进行综述,提出了硬脆材料塑性域加工未来的研究方向。

Review on ductile regime machining of hard and brittle materials

Hard and brittle materials have been widely used in aerospace and industry field due to its good physical and mechanical properties. But it is hard to machine this kind of material because of its high hardness and brittleness. Ductile-regime machining is an effective method to solve the defects in the processing of hard and brittle material. Hence,the critical conditions of brittle-ductile transition have been widely studied by domestic and foreign scholars. The current status of ductile regime processing mechanism,ductile regime processing model,surface/subsurface damage and the influencing factors on ductile regime machining is reviewed,and the future research directions of ductile regime machining for hard and brittle materials are proposed.
