摘　　要：利用真空实型铸渗工艺铸造出表面耐磨损,而芯部塑韧性好的钢基复合材料,用扫描电镜和金相显微镜对材料进行组织分析,并在14.5的分离式霍普金森压杆上对复合材料的耐磨层材料和基体材料进行了动态压缩力学性能实验,测定了耐磨层材料和基体材料在应变率为300/s的应力-应变曲线。The steel matrix composites are made by vacuum expandable pattern casting method. The surface of the matrix composites is wear resistance while the center of the composites is steel with good toughness. Microstructure characteristic is analyzed on SEM and metallography microscope. The dynamic mechanical properties of the wearable layer material and the matrix are tested on Ф14.5 spht Hopkinson pressure bar. The stress - strain curves of the wearable layer material and the matrix are drown out at the strain rate of 300/s.
