摘要：
This letter reports the effect of repeated melting of the ingots on the glass-forming ability (GFA) of Zr60Al15Ni25 and Zr65Al7.5Ni10Cu17.5 alloys. The results indicate that the glass transition temperature T-g and the onset temperature of crystallization T-x of Zr(60)A(15)Ni(25) alloy increase as melting times increase. However, the repeated melting of the ingot brings only a little change to Zr65Al7.5Ni10Cu17.5 glassy alloy. Within the framework of structure heredity and thermodynamics, the reason for the improvement of the GFA of alloys is discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
