摘要：
The influence of the presence of ceramic particles on the twinning mechanism in magnesium matrix composites was measured using synchrotron radiation diffraction during in situ compressive tests. As with the unreinforced alloys, the plasticity of extruded composites is controlled by the < 1 0 (1) over bar (1) over bar > {1 0 (1) over bar 2) tensile twining process. However, the volume fraction of twins is rapidly saturated as the volume fraction of reinforcement increases. SiC particles balance the tensile stress generated by twins during plastic deformation.
