Tensile Strain Hardening Behavior and Fractography of Superalloy GH39

Tensile Strain Hardening Behavior and Fractography of Superalloy GH39

The strain hardening behaviour and fractography of superalloy GH39 was investigated by tensile test at different strain rates. Results indicate that strain hardening behaviours are different during the deformation process. True stress-strain curve obeys the Hollomon relationship partly. The strain h...
