磨球碰撞过程中粉末的温升程度对于高能球磨固态反应的研究是一个基本问题。本文从碰撞理论出发，建立了球磨温度效应和工艺条件的关系，进行了理论计算分析。实测了不同工艺条件下Ａｌ－５０ａｔ％Ｃｕ粉末球磨时的温度效应，结合反应过程中组织结构分析，表明了理论分析是适当的。球磨时粉末温升和工艺条件密切相关，在本文实际的工艺条件下，粉末的最高温度不超过１６０℃，因而高能球磨固态反应是一个较低温度下进行的反应过程。
The temperature rise of the powder during ball milling is a fundamental issue for the study of the solid state reaction of high energy ball milling. Based on the collision theory, this paper establishes the relationship between the ball mill temperature effect and the process conditions, and carries out theoretical calculation and analysis. The temperature effect of Al-50at% Cu powder ball milling under different process conditions was measured. The analysis of the microstructure during the reaction showed that the theoretical analysis is appropriate. Ball milling powder temperature and process conditions are closely related to the actual process conditions in this article, the maximum temperature of the powder does not exceed 160 ℃, and thus high-energy ball mill solid state reaction is a lower temperature for the reaction process.
