金属材料的热处理是将固态金属或合金,采用适当的方式进行加热、保温和冷却,有时并兼之以化学作用和机械作用,使金属合金内部的组织和结构发生改变,从而获得改善材料性能的工艺。热处理工艺是使各种金属材料获得优良性能的重要手段。金属热处理在改善材料各种性能的同时,热处理变形是不可避免的,并且会直接影响到工件的精度、强度、噪声和寿命,因此对于精度要求较高的零件要尽可能减小其变形量,本文着重分析温度是控制变形的关键因素的同时罗列几点次要因素及减小措施。
Heat treatment of metal materials is the solid metal or alloy, the appropriate way to heat, heat and cooling, and sometimes both by chemical and mechanical action, so that the internal structure of the metal alloy and structure changes, resulting in improved material properties of the process . Heat treatment process is an important means to get good performance of various metal materials. Metal heat treatment to improve the performance of various materials at the same time, heat treatment deformation is inevitable, and will directly affect the accuracy of the workpiece, strength, noise and life expectancy for the higher precision parts to minimize the amount of deformation, This article focuses on the analysis of temperature is a key factor in controlling deformation, while listing a few key factors and reducing measures.
