Abstract:
Zr-based bulk metallic glass possesses is the highest potential as a structural material among metallic glasses. However, the production conditions have a great effect on its glass-forming ability (GFA) and mechanical characteristics. In this paper, an attempt is made to find the effect of a hereditary structure on the GFA and mechanical properties of a solid Zr52.8Cu29.1Ni7.3Al9.8Y1 bulk metallic glass in order to evaluate the possibility of using precursor, solid binary alloys that have a hereditary relation to the liquid phase. It is found that the GFA and stability of Zr52.8Cu29.1Ni7.3Al9.8Y1 bulk metallic glasses prepared in the hereditary process are higher than conventional samples and increase with the increasing quenching temperature. At a quenching temperature of 1523 K, the hereditary process can improve the supercooled liquid region ¦¤Tx from 33 K to 55 K and the compressive strength from 1555 MPa to 1652 MPa.
