本文研究了钒对高速旋转Ti-Zr-Ni-Cr非晶薄带力学性能的影响。结果表明，在Ti-Zr-Ni-Cr非晶合金中添加钒，可明显提高合金的力学性能。在45 m/s速度下快速凝固的Ti-Zr-Ni-Cr（V= 0，V= 0.1）薄带为非晶组织。但Ti-Zr-Ni-Cr-V合金的非晶结构比不含V的合金更加均匀。特别是Ti-Zr-Ni-Cr-V非晶薄带显示出更好的机械性能，非晶薄带样品的拉伸强度（）从V = 0的542 MPa显著增加到V = 0.1的675 MPa。伸长率（δ）从V = 0时的1.1%增加到V = 0.1时的1.29%。V = 0的非晶薄带断口呈现较多的解理特征，为明显的脆性断裂。V = 0时，非晶带的断裂面更像是脉状图案，这归因于局部粘度的变化。在Ti-Zr-Ni-Cr非晶合金中添加V可能有利于提高合金的流变单位和自由体积的大量积累。它有助于非晶薄带的机械性能，特别是拉伸强度和塑性变形。
In this paper, the effects of vanadium addition on the mechanical properties of Ti-Zr-Ni-Cr amorphous ribbons with high spinning speed were studied. It was found that the mechanical properties of samples were obvious promoted by adding vanadium into Ti-Zr-Ni-Cr amorphous alloys. The rapidly solidified Ti-Zr-Ni-Cr (V= 0,V= 0.1) ribbons at a speed of 45 m/s is an amorphous structure. But the amorphous structure of Ti-Zr-Ni-Cr-V alloys is even more uniform than that of the V-free alloys samples. In particular, Ti-Zr-Ni-Cr-V amorphous ribbons showed better mechanical properties that the tensile strength () of the amorphous ribbons samples that had been significantly increased from 542 MPa forV= 0–675 MPa forV= 0.1. The elongation (δ) exhibited a tiny increase from 1.1% forV= 0–1.29% forV= 0.1. The fractured surface of amorphous ribbons forV= 0 showed more cleavage features, it was the obviously brittle fracture. The fracture surface for amorphous ribbons forV= 0 were more vein-like patterns, they are attributed to a local change of viscosity. It’s likely that adding V into Ti-Zr-Ni-Cr amorphous alloys is beneficial to enhance rheological units and massive accumulation of free volume in ribbons. It contributes to mechanical properties, especially for the tensile strength and the plastic deformation of the amorphous ribbons.
