摘要: Abstract Deformed microstructure and mechanical properties of AM60B magnesium alloy under hypervelocity impact at a speed 4 km s−1 were studied through optical microscope (OM), scanning electron (SEM), transmission (TEM) indenter technique. The results show that the deformed below crater can be classified as three zones, i.e. dynamic recrystallization zone, high density deformation twin zone low zone. refined equiaxed recrystallized grains adjacent to formed, which should attributed twining-induced mechanism. { 1 0 ¯ 2 } , twins are confirmed selected area diffraction (SAED) microhardness yield strength in near much higher than matrix, strain hardening grain refining.
