采用拉压对称的机械应变控制, 研究了Ti-6-22-22合金在200~400℃和200~520℃两个温度范围的热机械疲劳(TMF)行为. 结果表明,
在200~400℃内, 同相和反相热机械疲劳寿命均高于400℃等温疲劳寿命; 在200~520℃范围, 反相热机械疲劳寿命明显低于520℃等温疲劳寿命...

A Voronoi cell element, formulated with creep, thermal and plastic strain was applied for investigation of thermo-mechanical fatigue behavior for particulate reinforced composites. Under the in-phase fatigue loading, the maximum of tensile deformation at the maximum given loading are larger than tha...
