通过高温压缩试验，研究了块体金属玻璃(BMG)在过冷液相区(SCLR)中的流变行为和热塑性变形，并绘制了加工图。结果表明，现有合金在SCLR中的流动应力对温度和应变率非常敏感。流动应力随温度的升高和应变速率的降低而减小。该合金的粘滞系数在1011Pa.s~109Pa.s之间，并随温度和应变速率的增加而减小。当应变速率大于5 × 10−3S−1时，合金经历了从牛顿流体到非牛顿流体的转变。在深SCLR中，高温压缩后的表面轮廓显示出类似字母N的形状。合金的最佳热加工区域为低应变率的688Cu18Ni10.12Al10合金的 K-708 K和高应变率的708 K-723 K。
In this paper, the rheological behavior and thermoplastic deformation of Zr61.88Cu18Ni10.12Al10bulk metallic glasses (BMGs) in the supercooled liquid region (SCLR) were studied by high temperature compression tests and a processing map was constructed. The results indicated that the flow stress of present alloy in the SCLR is very sensitive to temperature and strain-rate. The flow stress decreases with increasing temperature and decreasing strain-rate. The viscosity coefficient of the present alloy ranges from 1011Pa.s to 109Pa.s and decreases with increasing temperature and strain-rate. When the strain-rate is greater than 5 × 10−3s−1, the Zr61.88Cu18Ni10.12Al10alloy undergoes a transition from Newtonian fluid to non-Newtonian fluid. The surface profile exhibited a similar shape of the letter ‘N' after high temperature compression in the deeply SCLR. The optimum hot processing region of Zr61.88Cu18Ni10.12Al10alloy is 688 K–708 K with a low strain-rate and 708 K–723 K with a high strain-rate.
