Microstructure evolution of as-extruded Zn–0.62Mn alloys during room temperature compression

Abstract

The microstructure evolution of Zn–0.62Mn alloys during the room temperature compression with different strains was investigated by scanning electron microscope and X-ray diffraction. The results showed that with the increasing compression strains, the refined dynamic recrystallization grains increase gradually, and some grains rotate. It can also be found that the compression strain promotes the transformation from small-angle grain boundary to large-angle grain boundary. The highest basal textural can be obtained after the room-temperature compression with 80% strain. These results indicate that the microstructure evolution of as-extruded Zn–0.62Mn alloys during the room-temperature compression can be attributed to the grain refinement, grain boundary variation and texture changes.

“…In addition to alloying elements, processing and heat treatment techniques, such as casting, equal channel angular pressing (ECAP), hot extrusion, rolling, accelerated cooling, and annealing processes, play a crucial role in the mechanical properties and corrosion rate of alloys. Appropriate processing and heat treatment can optimize the mechanical and corrosion properties of alloys to meet clinical requirements [ 93 , [96] , [97] , [98] , [99] , [100] , [101] ]. Regardless of alloy optimization or processing techniques, they both affect the grain refinement and alloy uniformity, thereby influencing the corrosion rate and uniformity.…”
