摘要
Abstract
This paper proposes a nonlinear elastoplastic model and uses the finite element method to study the thermal residual stress in 3D-Cf/Mg and its modification after different treatments. Then an experimental investigation was realized by XRD, which indicates the influences of different treatments on thermal residual stress. The result shows that after a cold-treatment at -196℃ , the average thermal residual stress can decrease from 169.06 MPa to 55. 29 MPa, while the thermal residual stress changes little after a heat-treatment. This calculating result agrees well with the experimental results and proves that the cold-treatment can reduce the thermal residual stress in 3D-Cf/Mg.关键词
