锆基块体金属玻璃（Zr基BMG）作为活塞-气缸高压装置的气缸材料具有优异的性能，并且特别用于中子散射。由外径为8.8/2.5 mm的Zr基BMG圆柱体组成的活塞-圆柱体承受高达1.81 GPa的压力，并在2.0 GPa下破裂，压力值由铅的超导温度决定。Zr基非晶合金的中子衰减与TiZr零散射合金相近，但比CuBe合金透明。在Zr基块体玻璃的中子衍射图中没有观察到尖锐布拉格反射的污染。Zr基BMG的磁化率与CuBe合金的磁化率相似，这导致了在压力下测量磁性能的潜在应用。
Zirconium-based bulk metallic glass (Zr-based BMG) has outstanding properties as a cylinder material for piston-cylinder high pressure apparatuses and is especially useful for neutron scattering. The piston-cylinder consisting of a Zr-based BMG cylinder with outer/inner diameters of 8.8/2.5 mm sustains pressures up to 1.81 GPa and ruptured at 2.0 GPa, with pressure values determined by the superconducting temperature of lead. The neutron attenuation of Zr-based BMG is similar to that of TiZr null-scattering alloy and more transparent than that of CuBe alloy. No contamination of sharp Bragg reflections is observed in the neutron diffraction pattern for Zr-based BMG. The magnetic susceptibility of Zr-based BMG is similar to that of CuBe alloy; this leads to a potential application for measurements of magnetic properties under pressure.
