METHOD FOR DETERMINING SOFTENING TEMPERATURE OF COPPER AND COPPER ALLOY

摘要

A method for determining the softening temperature of copper and a copper alloy, comprising the following steps: 1) selecting several kinds of samples of the same material, and performing air-cooling on the samples after being insulated and annealed separately at different temperatures; 2) separately determining the tensile strength of an original sample and the samples subjected to insulation and annealing treatments; 3) plotting determined tensile strength data onto a temperature-tensile strength curve; 4) taking a corresponding temperature in the temperature-tensile strength curve at which the tensile strength drops to a certain value of tensile strength of the original sample as the softening temperature of the material. By means of using the tensile strength instead of hardness to determine the softening temperature of a fine material of copper and copper alloy, the detection efficiency may be effectively improved, thus reducing costs; and the described method may be widely applied to the determination of the softening temperature of a fine material of copper and copper alloy.
