Deformation behavior of ultra-fine-grained Mg-0.3 at% Al alloy in compression

Fine and coarse grained (5–20 μm) and ultra-fine-grained (down to 1 μm) samples of a binary Mg-Al alloy were fabricated by extrusion at various temperatures. When tested in compression, a slight stress drop was observed after yielding, followed by a plateau in flow stress. This behavior is typical o...
