长期以来 ,金属塑性加工理论研究多限于对变形的力学分析 ,忽略了热效应及传热等影响。在金属成形过程中 ,塑性变形功不断转化为热 ,使变形体内温度不均匀变化 ,因而使变形体内力学性能亦随之改变 ,反过来影响变形的力学过程。对变形和传热两过程以及它们的相互影响进行研究 ,? For a long time, the theory of metal plastic processing is mostly limited to mechanical analysis of deformation, ignoring the effects of heat and heat transfer. In the metal forming process, the plastic deformation work continuously transformed into heat, so that deformation of the body temperature varies unevenly, so that deformation of the mechanical properties also change, which in turn affect the deformation of the mechanical process. The deformation and heat transfer of the two processes and their interaction study?
