Formation of Ti-Zr-Cu-Ni bulk metallic glasses

Formation of bulk metallic glass in quaternary Ti-Zr-Cu-Ni alloys by relatively slow cooling from the melt is reported. Thick strips of metallic glass were obtained by the method of metal mold casting. The glass forming ability of the quaternary alloys exceeds that of binary or ternary alloys containing the same elements due to the complexity of the system. The best glass forming alloys such as...

Glass-Forming Ability and Early Crystallization Kinetics of Novel Cu-Zr-Al-Co Bulk Metallic Glasses

In recent years, CuZr-based bulk metallic glass (BMG) composites ductilized by a shape memory B2 CuZr phase have attracted great attention owing to their outstanding mechanical properties. However, the B2 CuZr phase for most CuZr-based glass-forming compositions is only stable at very high temperatures, leading to the uncontrollable formation of B2 crystals during quenching. In this work, by in...

Zr–Cu–Ni–Al bulk metallic glasses with superhigh glass-forming ability

Zr–Cu–Ni–Al quaternary amorphous alloy compositions with varying glass-forming ability are developed by an efficient method of proportional mixing of binary eutectics. The critical diameter of the glassy sample is improved from 6 mm for Zr53Cu18.7Ni12Al16.3 to 14 mm for Zr50.7Cu28Ni9Al12.3 by straightforwardly adjusting the eutectic unit’s coefficients. The drastic improvement in GFA is attribu...

Development of Ni- and Cu-Free Zr-Based Bulk Metallic Glasses for Biomedical Applications

Two Niand Cu-free bulk metallic glasses (BMGs) of Zr65Pd17:5Fe10Al7:5 and Zr65Pd12:5Ag5Fe10Al7:5, with a critical casting diameter of 6mm and a compressive strength above 1500MPa, were developed. While the Zr65Pd17:5Fe10Al7:5 alloy showed little plastic strain before fracture, the Zr65Pd12:5Ag5Fe10Al7:5 alloy exhibited much larger plasticity by the relatively stable, intermittent propagation of...

Formation and Corrosion Behavior of Mechanically-Alloyed Cu–Zr–Ti Bulk Metallic Glasses

Cu60Zr30Ti10 metallic glass powder was prepared by mechanically alloying a mixture of pure Cu, Zr, and Ti powders after 5 h of milling. Cu60Zr30Ti10 bulk metallic glass (BMG) was synthesized by vacuum hot pressing the as-milled Cu60Zr30Ti10 metallic glass powder at 746 K in the pressure range of 0.72–1.20 GPa, and the structure was analyzed through X-ray diffraction and transmission electron mi...
