ALLOY OF TUNGSTEN (W) AND COPPER (CU) HAVING FUNCTIONALLY GRADED MATERIAL (FGM) LAYERS, METAL MATERIAL HAVING THE SAME AND MANUFACTURING METHOD FOR ALLOY OF W AND CU

摘要

Disclosed are a tungsten-copper alloy, a metal material having the same and a fabrication method for the tungsten-copper alloy, the fabrication method including generating tungsten-copper composite powders such that tungsten is coated on copper powders and the composition ratios of copper and tungsten are different, sequentially laminating the tungsten-copper composite powders to create a plurality of layers, having sequentially increasing or decreasing contents of tungsten, and sintering the plurality of layers under conditions of temperature and time preset for generation of tungsten-copper alloy, whereby the tungsten-copper alloy and high thermal conductivity and fabrication reliability by virtue of precise morphologies can be created.
