Texture evolution of an Al-8Zn alloy during ECAP and post-ECAP isothermal annealing [PDF]
Materials Characterization, 2019 Abstract In this work, the texture evolution of an Al-8 wt% Zn alloy during equal channel angular pressing (ECAP) and post-ECAP isothermal annealing was systematically investigated by electron backscatter diffraction (EBSD). Special attention is paid to the influence of static recovery and recrystallization on ECAP texture.
