摘要： 分析了温度升高时材料产生热膨胀的同时伴随着力变形的变化,在精确测定材料的热变形时,必须考虑这种力变形的变化.文中还提出了零件热变形系数的概念,并讨论了零件热变形系数与材料热膨胀系数的关系.

关键词: 热变形系数, 热变形, 力变形, 热膨胀系数

Abstract: This paper analyzes the change of the forced deformation that occurs along with thermal expansion of material at rising temperature. The change of the forced deformation must be taken into account in the accurate measurement of thermal deformation of metal. The concepts of the thermal deformation coefficient and the relation between the coefficient of thermal deformation and that of thermal expansion are discussed.

Key words: thermal deformation, coefficient of thermal deformation, coefficient of thermal expansion, forced deformation
