| Abstract Scope |
The high strength and low ductility of body-centred cubic (BCC) high entropy alloys (HEAs) both result from the severe lattice-distortion effect as measured by the atomic mismatch (δ). In this investigation, we report a novel non-equiatomic TiZrNbVFeCr - based high entropy alloy, which were fabricated through a conventional arc-melting process. This alloy solidifies as not a single phase, instead at least two different phases were predicted by thermodynamic parameters. Vickers Microhardness measurements revealed values around 500 HV for a hard phase, while an average value of 88.2 HV was calculated for the soft phase. DRX analyses as well as optical and electronic microscopy were used to investigate the microstructure of the alloy. In addition to those, other mechanical properties were determined by uniaxial compression tests under different strain rates. |
