Synthesis of nanocrystalline carbide in tungsten alloy by mechanical alloying and annealing

Amorphous tungsten alloys embedded with nanocrystalline carbide were obtained through crystallization of a completely amorphized tungsten alloy, which has first been synthesized by mechanical alloying. Structural characterization, showed the formation of amorphous structure after mechanical alloying a mixture of elemental tungsten and iron powders for about 150 h. Partial nanocrystalline phases within the amorphous matrix were formed through annealing the amorphous tungsten alloy at 1075 °C.
