Abstract

The Cu-Si-Zn alloys in the composition near Cu 45 wt%, Si 5 wt% and Zn 50 wt% (γ solid solution) were investigated by means of thermal analysis and microscopic examination. A transformation of the γ solid solution, γ\ ightleftarrowsγ′, was found below 457°C in a range of the ternary system, and the transformation temperature lowers with decrease of Si content in the solid solution. This transformation may proceed by a diffusionless mechanism and the low temperature phase γ′ seems to have a distorted γ-brass type structure. The twin-like figure appeared in the γ′ phase of the slowly cooled specimens is attributed to the transformation from γ to γ′.<BR>By measurements of electrical resistance of the alloys near the β solid solution, it was found that Si has little effect on the temperature of the order-disorder transformation in the β solid solution.
