| Abstract: | In this study, ternary additives Ni Fe Cu were selected to fabricate tungsten alloys with both high density and good mechanical properties at a low temperature of 1 573 K. By adding 2wt pct copper, a dense 93W 3.5Ni 1.5Fe 2.0Cu alloy with high bending strength was achieved successfully by hot pressing sintering. The mechanism of the densification of W Ni Fe Cu system heavy alloys was mainly investigated. |
