|
For meeting the technological requirements of aircraft forgings,the forging process of Al-2.18Cu-1.53Mg-0.97Fe-0.96Ni aluminum alloy on the industrial production line was studied,mainly the influences of its temperature,rate and extent of deformation,heat-treatment data on the microstructures and mechanical properties of this alloy,with the methods of tests of mechanical properties and hardness and micro-structural observation.Production process and technological parameters to forge the alloy were determined.The experimental results show that the temperature range to forge the alloy should be 350~470 ℃,its solution treatment 525~535 ℃,its aging temperature 195 ℃,and its aging holding time 12 h.
