Abstract Scope |
The competitive growth principle that governs phase selection during solidification has been utilized to investigate the formation of metallic glasses in binary and ternary eutectic systems. The model indicates that the glass formation is due to the suppression of all primary competing crystalline phases and eutectic structures. A new criterion gauging the globally optimum glass-forming ability in eutectic systems is derived, with a corollary that the best glass-forming composition zone can be either symmetric, or asymmetric, about the eutectic composition. The practical implementation and significance of the strategies is demonstrated by discovering bulk metallic glasses in Zr-based eutectic systems. |
