Abstract

Abstract: Effects of different heat treatment systems and cold deformation on linear expansion coefficient of the constant expansion alloy 4J32C were studied. The results show that the linear expansion coefficient of the alloy is not significantly changed by small amount of cold deformation. With the increase of solution treatment temperature, the linear expansion coefficient of the alloy decreases gradually, reaches the lowest value at 850 ℃, and then increases slightly with the increase of solution temperature. The linear expansion coefficient of the alloy can be appropriately increased by prolonging the stabilization treatment time or increasing the stabilization treatment temperature.

Key words: constant expansion alloy, 4J32C alloy, linear expansion coefficient, heat treatment, cold deformation
