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...
متن کاملFabrication and Mechanical Behavior of Ex Situ Mg-Based Bulk Metallic Glass Matrix Composite Reinforced with Electroless Cu-Coated SiC Particles
Magnesium-based bulk metallic glass matrix composites (BMGMCs) have better plasticity than the corresponding bulk metallic glasses (BMGs); however, their strength and density are often compromised due to the fact that the effective reinforcement phase is mostly plastic heavy metal. For lightweight SiC-particle reinforced BMGMCs, interface wettability and the sharpness of the particles often red...
متن کاملThe Microstructural Evolution and Mechanical Properties of Zr-Based Metallic Glass under Different Strain Rate Compressions
In this study, the high strain rate deformation behavior and the microstructure evolution of Zr-Cu-Al-Ni metallic glasses under various strain rates were investigated. The influence of strain and strain rate on the mechanical properties and fracture behavior, as well as microstructural properties was also investigated. Before mechanical testing, the structure and thermal stability of the Zr-Cu-...
متن کاملMechanical Properties of Bulk Metallic Glasses and composites
We have studied the mechanical properties of monolithic bulk metallic glasses and composite in the La based alloys. La86-yAl14(Cu, Ni)y (y=24 to 32) alloy systems was used to cast the in-situ structure and subsequently tested under compression. We found that the ductility of the monolithic is actually poorer than that of the fully crystalline composite.
متن کاملPhase Separation and Crystallization in Cu-Zr Metallic Glasses
The structural behavior of rapidly quenched Cu-Zr amorphous alloys was analyzed. High energy X-ray diffraction patterns and atomic pair correlation functions exhibit monotonic changes with composition. The experimental results can be well described by a solid solution-like replacement of Cu and Zr atoms in the whole composition range. No indications are observed that would support the existence...
