| Abstract Scope |
High Entropy Alloys are a new and exciting branch of metallurgy known for corrosion resistance and high hardness properties of interest in demanding and premium high-security applications, where the hardest (>700HV) and strongest (tensile UTS> 1200 MPa) materials are required, whilst also being lightweight (<7 g/cc) in transport applications. These properties are normally found from precipitation hardened, maraging or tool steels with high tensile strengths and ductility (7-10% uniform elongation).
The HEA system Alx(CoCrCuFeNi)1-x holds the promise of high hardness and relatively low density, but only compressive properties have been examined because of the predominantly BCC phases in the higher Al compositions. For a range of both equimolar and non-equimolar variants of this HEA, microstructure, composition and properties are evaluated via XRD, SEM/EDS, hardness testing and high throughput punch, to see if there is a balance of properties which can match those of the benchmark steels. |
