摘　　要：本文通过测试铜合金在连续加热过程中电阻率的变化研究了铜合金的连续加热时效动力学。提出了用时效过程中电阻率的减小值Δρ作为描述时效过程的参数。在此基础上,建立了连续加热时效动力学图。在等速加热时效过程中,利用电阻率与温度呈线性关系这一特点,提出了一种计算Δρ的方法。测出了Cu-Cr-Zr合金以0.075～1.6℃/min加热速率进行加热时的Δρ与温度的关系。The variation of resistivity was tested for an copper alloy （Cu-Cr-Zr） during continuous heating to study the relevant aging kinetics. It was suggested that the decrement of the resistivity in aging process, △p, is taken as a parameter to describe the aging process. Then, based on experimental data, a diagram of aging kinetics during continuous heating is given. Taking advantage of the linear relationship between resistivity and temperature in the aging process at constant heating rate, a method is proposed to calculate △p, and the relationship between △p and temperature of the copper alloy is obtained when the heating rate is 0.075-1.6℃/min.
