热挤压对SiC_w/MB15镁基复合材料组织和性能的影响
Effects of Hot Extrusion on the Microstructure and Mechanical Properties of the Composite SiCw/MB15
【摘要】 利用SEM,TEM,X射线衍射仪等方法,研究了挤压对SiCW/MB15镁基复合材料组织和性能的影响。结果表明:热挤压后复合材料组织更加均匀,SiC晶须长轴与挤压方向平行,晶须的增强作用得到了充分的发挥,显著提高了SiCW/MB15镁基复合材料的力学性能。
【Abstract】 The effects of hot extrusion on the microstructure and tensile properties of SiCw/MB15 were investigated by means of SEM,TEM and X- ray diffraction.After hot extrusion the microstructure was found to be homogeneous and with the axes of SiC whiskers are parallel to the extrusion direction the alignment of the SiC whiskers was found to improve the mechanical properties of composite.
