Microstructural development and mechanical properties of tungsten heavy alloy, WHA, with FeNiCoCrMn high entropy HEA, binder were investigated compared to conventional WHA using Fe–Ni binder. Both WHAs, HEA binders, fabricated by hot isostatic pressing at a temperature 1450 °C in an argon environment. Scanning electron microscopy revealed that binders possessed uniform well-refined microstructures. Energy dispersive spectroscopy X-ray diffraction, XRD, validated the formation composition existing as skeletal network surrounding grains. exhibited overall increase 42% micro Vickers hardness values. Furthermore, values alloy also seen rise when However, sample was undergo faster strain hardening premature failure, leading lower ultimate strength reduced ductility.
