Abstract

The invention belongs to the field of new materials and discloses Zr-Al-Ni-Cu bulk metallic glass achieving room temperature compression superplasticity. Zr with purity being 99.99wt%, Al with purity being 99.99wt%, Ni with purity being 99.99wt% and Cu with purity being 99.99wt% are smelted according to a vacuum melting method, and then a vacuum suction pouring method is adopted, so that the Zr-Al-Ni-Cu bulk metallic glass with the diameter being 2 mm is obtained. The Zr-Al-Ni-Cu bulk metallic glass has room temperature compression superplasticity and comprises ingredients of Zr62Al12Ni15Cu11, Zr62.5Al11.3Ni13.85Cu12.35, Zr63Al10.6Ni12.7Cu13.7, Zr63.5Al10Ni11.75Cu14.75, Zr64Al9.3Ni10.6Cu16.1, Zr64.5Al8.6Ni9.45Cu17.45, Zr65Al8Ni8.5Cu18.5, Zr65.5Al7.3Ni7.35Cu19.85 and Zr66Al6.6Ni6.2Cu21.2.

Description

technical field [0001] The invention relates to a series of Zr-Al-Ni-Cu bulk metallic glasses with room temperature compressive superplasticity. Background technique [0002] Zirconium-based bulk metallic glasses have excellent physical and chemical properties, especially some zirconium-based bulk metallic glasses exhibit good room temperature plasticity and biocompatibility, which make them of great interest in the fields of structures and biomaterials. Application prospects. However, the room temperature brittleness of most zirconium-based bulk metallic glasses greatly limits their applications, so it is of great significance to prepare zirconium-based bulk metallic glasses with good room temperature plasticity, especially room temperature superplasticity. Contents of the invention [0003] The object of the present invention is to provide a series of Zr-Al-Ni-Cu bulk metallic glasses with room temperature compressive superplasticity. [0004] The object of the pres...
