为了解非晶合金的切削机理,对大块非晶合金Zr41.2Ti13.8Cu12.5Ni10.0Be22.5进行了不同切削深度的切削实验,然后用扫描电镜、X光衍射仪和测力系统对切屑形态和切削力进行观察和测量。实验结果表明:Zr基非晶合金在受拉的时候,比全脆性材料有更好的塑性表现,其切屑形态独特且具有塑性剪切带特征;主切削力Fz随切削深度的增加而增长,但Fx和Fy则几乎没有变化。 In order to understand the cutting mechanism of amorphous alloy, cutting experiment of different depth of cut of the bulk amorphous alloy Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 was carried out. Then, the cutting depth was measured by scanning electron microscopy, X-ray diffractometer and force measuring system Morphology and cutting force were observed and measured. The experimental results show that the Zr-based amorphous alloy has a better plasticity than the brittle material when subjected to tension, and the unique chip shape and plastic shear band characteristics. The main cutting force Fz increases with the depth of cut, However, Fx and Fy are almost unchanged.
