A method for forming tungsten-refractory metal alloy powders, and tungsten- refractory metal alloy powders formed by the method. The method includes mixing a majority portion by weight of a base tungsten powder with a minority portion by weight of a base refractory metal powder to form a mixture, which is then milled for a period of time sufficient to at least partially mechanically alloy the base tungsten powder and base refractory metal powder together to form at-least-partially- mechanically-alloyed particles, which are then heat treated to a temperature sufficient to promote diffusion between tungsten and the refractory metal and obtain agglomerations of particles having only a tungsten phase, which are then milled to break up the agglomerations of particles and obtain the tungsten-refractory metal alloy powder.
