摘要：

The glass-forming ability (GFA) and thermal stability of (Zr65Al7.5Cu27.5)(100-x)Ti-x (x = 0 similar to 15; in at%) alloys have been investigated. It was revealed that a certain amount of Ti addition could improve the GFA of Zr65Al7.5Cu27.5 alloy effectively. The best bulk metallic glass (BMG) forming composition was found at (Zr65Al7.5Cu27.5)(93)Ti-7. Bulk glassy samples with diameter of 7 mm were made by means of copper mold casting. Further Ti additions deteriorated GFA and led to the precipitation of icosahedral phase, and 3 mm quasicrystalline cylinder was obtained at (Zr65Al7.5Cu27.5)(90)Ti-10. Room temperature compression testing showed that the quasicrystalline alloy had a fracture strength of 1875 MPa, being 300 MPa larger than that of the (Zr65Al7.5Cu27.5)(93)Ti-7 monolithic BMG.
