Casting and characterising novel high entropy alloys

The progression of materials has furthered the progression of human civilisation, as with the advent of alloys, the discovery and experimentation into high entropy alloys has developed. This document will demonstrate that a previously novel high entropy alloy can be effectively cast and characterised with the resources available to Macquarie University. Casting is achieved through the use of an induction furnace. Prior to analysis the samples must be mounted and polished. Characterisation involves hardness testing to determine the Vickers Hardness, wet chemical etching and use of a scanning electron microscope, to determins phase structure and grain size. Based on this information, the concept of future production of varied, and experimental, novel high entropy alloys is explored.
