Glass Formation, Chemical Properties and Surface Analysis of Cu-Based Bulk Metallic Glasses
This paper reviews the influence of alloying elements Mo, Nb, Ta and Ni on glass formation and corrosion resistance of Cu-based bulk metallic glasses (BMGs). In order to obtain basic knowledge for application to the industry, corrosion resistance of the Cu-Hf-Ti-(Mo, Nb, Ta, Ni) and Cu-Zr-Ag-Al-(Nb) bulk glassy alloy systems in various solutions are reported in this work. Moreover, X-ray photoe...
متن کاملFormation 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...
متن کاملRole of Alloying Additions in Glass Formation and Properties of Bulk Metallic Glasses
Alloying addition, as a means of improving mechanical properties and saving on costs of materials, has been applied to a broad range of uses and products in the metallurgical fields. In the field of bulk metallic glasses (BMGs), alloying additions have also proven to play effective and important roles in promoting glass formation, enhancing thermal stability and improving plasticity of the mate...
متن کاملMeasurement of low-temperature transport properties of Cu-based Cu-Zr-Ti bulk metallic glass
The transport properties, including electrical resistivity , thermopower S , and thermal conductivity of bulk metallic glass alloys Cu64Zr28.5Ti7.1, Cu62.3Zr23.7Ti10, Cu60.6Zr26.9Ti12.5 and Cu58.8Zr26.2Ti15 in the temperature range 10–300 K are reported. The temperature variations of electrical resistivity in these alloys, with a negative temperature coefficient, are found to be rather weak. Th...
متن کاملGlass-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...
