铸态大块非晶合金在室温拉伸载荷下无塑性应变断裂。然而，它是从分子动力学计算推断，玻璃的屈服面是类似的韧性金属之一。在这项研究中，单轴拉伸，单轴压缩，和简单的剪切试验进行了锆基大块金属玻璃在室温下的屈服面（断裂面）进行了实验检查。结果，锆基块状金属玻璃在室温下的变形主要由剪切应力控制，就像韧性金属的情况一样。
As-cast bulk metallic glasses fracture without plastic strain under tensile loading at room temperature. However, it is inferred from molecular dynamics calculation that the yield surface of the glass is similar to that of one of the ductile metals. In this study, uni-axial tensile, uni-axial compressive, and simple shear tests were carried out for zirconium-based bulk metallic glass at room temperature and the yield surface (the fracture surface) was inspected experimentally. As a result, the deformation of the zirconium-based bulk metallic glass at room temperature is dominated mainly by shear stress just like in the case of a ductile metal.
