利用铜模铸造法获得(Cu_(0.6)Zr_(0.3)Ti_(0.1))_(95)Nb_5块体非晶复合材料试样。该试样中均匀分布富Nb元素的枝晶相。结果表明,相比于非晶基体,枝晶具有更低的硬度值和弹性模量,在加载变形过程中,非晶基体和枝晶界面处产生应力集中,促使非晶基体中剪切带的萌生和分叉增殖,最终获得了约2200 MPa的压缩断裂强度和6.08%断裂应变。与其他Cu基非晶复合材料相比,所制备的(Cu_(0.6)Zr_(0.3)Ti_(0.1))_(95)Nb_5非晶复合材料断裂强度没有明显的降低,证明添加Nb元素是一种非常容易和有效制备实用高强度、高塑性非晶复合材料的方法。 The (Cu_ (0.6) Zr_ (0.3) Ti_ (0.1)) _ (95) Nb_5 bulk amorphous composite samples were obtained by copper mold casting. The sample is uniformly distributed Nb-rich dendrite phase. The results show that the dendrites have lower hardness and elastic modulus than the amorphous matrix. During the loading deformation, stress concentration occurs at the interface between the amorphous matrix and the dendrite, which promotes the initiation of shear bands in the amorphous matrix And bifurcation and finally obtained a compressive breaking strength of about 2200 MPa and a breaking strain of 6.08%. Compared with other Cu-based amorphous composites, the fracture strength of (Cu_ (0.6) Zr_ (0.3) Ti_ (0.1)) _95Nb_5 amorphous composites was not significantly reduced, Very easy and effective preparation of practical high strength, high plasticity amorphous composite method.
