文摘

Isothermal compressive deformation behaviors of a TiNiFe alloy are studied. EBSD technique has been used to evaluate the severity of deformation with induced the grain orientation spread (GOS) value. The development of recrystallizing grain boundaries is tracked in deformed grains with different GOS values. The continuous dynamic recrystallization is the dominated dynamic recrystallization mechanism.
