| 摘 要： | 以Al-10%(质量分数)Zr和Al-3%(质量分数)B合金为原料,在高能超声作用下采用熔体直接反应法成功地制备了ZrB2p/Al复合材料。利用X射线衍射仪、扫描电镜等分析了复合材料的物相和显微组织,并测试了其力学性能。结果表明,经过高能超声处理后,复合材料中的ZrB2颗粒尺寸更小,分布也更均匀。复合材料的抗拉强度、屈服强度和伸长率分别达到94、81MPa和14.5%,较未施加高能超声场的复合材料分别提高了10.6%、15.7%和16.0%。

| Abstract: | With high intensity ultrasonic treatment,a ZrB2 particle reinforced aluminum matrix composite was successfully fabricated by using the direct melt reaction method.The phase content and microstructure of composite were analyzed by using X-ray diffractometer(XRD) and scanning electron microscopy(SEM).The result shows that the size of ZrB2 particles in composite has become smaller and the distribution has been improved after high intensity ultrasonic treatment.The tensile strength,yield strength and the elongation of the composites reach to 94,81MPa and 14.5%,which are 10.6%,15.7% and 16.0% higher than those without ultrasonic assistance respectively. |
