摘要：
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 degrees C. (c) 2004 Elsevier B.V. All rights reserved.
