Abstract Scope |
High entropy metallic glasses have been under research recently due to the structural complexity of the high entropy alloy systems supporting the development of metallic glasses with the excellent glass-forming ability and unique properties. Although metallic glasses have high mechanical strength and hardness, they are brittle at room temperature in nature due to the lack of a crystal slip mechanism. In order to expand their potential uses in engineering, there is a great need to overcome the embrittlement problem. One of the potential solutions to increase the ductility of metallic glasses is to introduce nanocrystals into the glassy matrix through controlled devitrification. In this respect, we have investigated the mechanical properties of a newly developed high entropy metallic glass system ((Zr30Hf25Al20Ni10Co10Cu5)99.9Y0.1) in as-solidified and partially devitrified conditions. The mechanical properties based on the uniaxial compression test and nanoindentation tests will be investigated along with the transmission electron microscopy analysis. |
