【 摘 要 】

The effect of Al content and annealing temperature on the cold workability of CuAlMn alloys has been studied by testing machine, metallographic analysis and XRD method. The study results showed that because of martensite and ductile phase the cold workability of Cu-17.55Al-9.9Mn (at %) alloy was much better than Cu-19.1Al-9.9Mn (at %) alloy. Besides Al content, annealing temperature effects the cold workability of CuAlMn alloys. With the annealing temperature increasing from 525°C to 700°C, the cold workability of Cu-17.55Al-9.9Mn (at%) alloy increased gradually and reached 75%. However, the cold workability of Cu-19.1Al-9.9Mn (at %) alloys annealed from 525°C to 700°C was low. Furnace-cooling could be an effective annealing technique to improve the cold workability of Cu-19.1Al-9.9Mn (at %) alloy.
