Development of large high strength aluminum alloy component for spacecraft
Abstract
NKK developed and supplied a large aluminum alloy (7075-T7352) spacecraft component. Two major problems could arise in manufacturing this part by conventional production methods: difficulty in achieving the specified strength because of the very thick sections and difficulty in removing the residual stress from quenching because of the complex shape. NKK developed a production method that solved these problems. This paper describes the results of theoretical analysis on the generation and removal of residual stress, experimental studies on the removal of residual stress in small blocks, and full-scale tests to verify the selected method.
