| 摘 要： | 在工业条件下，采用球磨混料、机械压模成型以及真空粉末冶金法制备钛基复合材料。通过测量不同组分和烧结温度条件下试样的弯曲强度和硬度，以及观察其微观组织，结果发现：钛基复合材料的组分对其三点弯曲强度影响较大，三点弯曲强度167．4～602．9MPa，Ti／15W的三点弯曲强度达到602．9MPa；烧结温度对其硬度影响相对较大，洛氏硬度（HRC）31．4～63．8，Ti-3．5Mo-3．4Fe-1．1AI／12TiB的洛氏硬度达到63．8。

| Abstract: | In this paper, titanium matrix composites(TMCs) is prepared in industrial conditions with techniques about attrition ball milling, cold isostatic pressing and vacuum-sintered power metallurgy. Under certain temperature and component condition three-point bending strength and rockwell hardness of specimen are measured. Microscopic organization of specimen is also observed. The conclusion is that the influence of component on three-point bending strength of specimen is remarkable. Three-point bending strength of specimen ranges from 167. 4MPa to 602. 9MPa. Three-point bending strength of Ti/15W reaches 602.9MPa. The influence of temperature on hardness is relatively larger to others. Rockwell hardness of specimen ranges from 31.4HRC to 63. 8HRC. Rockwell hardness of ti-3. 5Mo-3.4Fe-1. 1Al/12TiB reaches 63. 8HRC. |
