Densification, microstructure and mechanical properties of 90W-4Ni-6Mn heavy alloy

► Densities around 99.7% for the 90W-4Ni-6Mn alloys were obtained. ► Lower temperature results in finer grains and better mechanical properties. ► A 1030 MPa ultimate tensile strength with a 25% elongation to failure was achieved. ► Insufficient coalescence process could lead to a poor performance in elongation. ► 90W-4Ni-6Mn with properties comparable to other WHAs can be obtained below 1200 °C.
