    Abstract
  • Coarse-grain is one of the main defects in multistage stretch forming of airplane skins for aluminum alloy. An experiment of different strain paths to 2024-O aluminum alloy was designed according to the deformation state and process in skin stretch forming. The experiment process was pre-stretch, quench heat treatment and microstructure analysis, from which the relationship between grain size and deformation before heat treatment was established. The critical pre-strains of different strain paths were obtained through grid strain measurement, and the critical pre-strain curve was determined. The finite element analysis of an airplane skin was carried out combined with the critical pre-strain curve, and the coarse-grain was controlled.
