研究了具有改善非晶形成标准的五元Zr基合金成分，并对这些合金的非晶形成能力、热稳定性和力学性能进行了研究。单片非晶结构已被确认为所有的组合物在5毫米棒由铜模铸造方法制备。在屈服应力约为2000 MPa的单轴压缩试验中，它们也表现出约12%的最大塑性应变。铸造温度对铸棒的压缩塑性有很大影响。
Quinary Zr-based alloy compositions with improved glass forming criteria have been sought and the glass forming ability (GFA), thermal stability and mechanical properties of these alloys have been investigated. Monolithic amorphous structure has been confirmed for all compositions in 5 mm rods prepared by a Cu-mold casting method. They also show large plastic strain maximum of about 12% under uniaxial compression test with yield stress of about 2000 MPa. The compressive plasticity of the cast rods was found to be influenced by the casting temperature to a great extent.
