| Abstract: | The influence of heat treatment processes on the strength.hardnese and fatigue crack propa-gating rate of a Cu-Ni-Al-Ti alloy was studied.The results show that the ccoling rate after solu-tion heat treatment has great influence on the properties of the alloy:namely,the larger the cool-ing rate,the higher the strength and the lower the plasticity.But the alloy can retain relativelyhigh strength even under air-cooling.With regard to the strength.it is advisable to adopt the fol-lowing process:solution heat treatment water cooling cold deformation aging.However,with regard to the combination of the strength,plasticity and fatigue crack propagating rate,it isadvisable to adopt the following process:solution heat treatment air-cooling cold deformation aging. |
