Abstract Scope The analogous rhenium effect of manganese in tungsten-molybdenum alloys was investigated. Nine tungsten alloys were prepared (W – X Mo – Y Mn, X = 5, 10, 15 at%, and Y = 2, 5, 8 at%). Samples were sintered for 1 hour at 1350C or 1425C. Besides the tungsten phase, the X-ray diffraction patterns and back scattered electron images show a manganese rich phase which is observed in all samples, while an oxide was also observed in those samples sintered at 1425C. The slight reduction in the lattice parameter of the tungsten phase is not consistent with the molybdenum or manganese content. The relative densities are 65-80% compared to theoretical due to closed porosity and incomplete reduction. Those alloys containing 5 at% manganese show a decrease in the Vickers hardness. This decrease, however, is about equal to one standard deviation of the measurement.
