Effect of Initial Grain Size on High‐Temperature Tensile Deformation and Microstructural Evolution of GH2907 Alloy
To investigate the effect of grain size on the tensile deformation behavior and dynamic softening mechanisms of GH2907 alloy at 500 and 600 °C, fine‐grained (FG) and coarse‐grained (CG) specimens were prepared via solution treatment. High‐temperature tensile tests were performed at 500 and 600 °C, combined with mechani...
