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。

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 in- dicate 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 K,c value were 10. 529,5. 142 and 3. 446 MPa · m^1/2 respectively.
