| 摘 要： | 采用铜模吸铸法制备了（Zr0.55Al0.1Ni0.05Cu0.30）100-xTix（x=0、2、4、6、8）板状哑铃型金属玻璃基复合材料试样。用X射线衍射（XRD）、岛津AG-10TA万能材料力学试验机和JSM-6700F场发射扫描电子显微镜（SEM）对试样的组织结构以及断裂韧性进行了测试。结果表明,当x=0、2、4时,试样为非晶-晶体复合材料,当x=6、8时,试样为晶体材料。表明通过调整Ti的含量可以制备出金属玻璃基复合材料。采用三点弯曲法测定了复合材料的断裂韧性,当x=0、2、4时,试样的断裂韧性KIC值分别为10.529、5.142和3.446MPa.m1/2。

| Abstract: | The dumbbell-shaped metallic glass based composites of(Zr0.55Al0.1Ni0.05Cu0.30)100-xTix(x=0,2,4,6,8) were prepared by copper mold casting method.Microstructure and fracture toughness of samples were studied by X-ray diffraction(XRD),universal testing machine and scanning electron microscope(SEM).The results indicate that metallic glass based composites can be fabricated by adjusting Ti addition.The structure of the alloys were composed of metallic glass and crystal when the Ti content was x=0,2,4 and the structure of the alloys were crystal when the Ti content was x=6,8.The fracture toughness of composites which Ti content was x=0,2,4 were measured by three point bending method,and the KIC value were 10.529,5.142 and 3.446 MPa·m1/2 respectively. |
