Abstract

This study is carried out to provide detailed hot deformation information on aluminum alloy AA2219-O. The uniaxial tensile tests are carried out to study the hot deformation behaviors. The test temperature ranges from 415°C to 515°C, and the strain rates are 0.001s-1 and 0.01s-1. Additionally, the analysis of the strain rate sensitivity coefficient indicates that the AA2219-O exhibits the trend of superplasticity at temperatures above 475°C.
