Deformation behavior and microstructure evolution mechanism of 5vol.% (TiBw + TiCp)/Ti composites during isothermal compression

Isothermal compression tests of as-cast 5vol.% (TiBw + TiCp)/Ti composites were conducted in the deformation temperature ranging from 900 to 1100 °C and strain rate ranging from 0.001 to 1.0 s−1. The thermal deformation behavior and microstructure evolution mechanism of the material are studied to optimize the process parameters. Meanwhile, the flow stress-strain curves were measured. The activation energy decreases with increasing of...
