【Know Tungsten】Tungsten Copper Rapid Directional Solidification

tungsten copper rapid directional solidification picture

Tungsten copper rapid directional solidification preparation of tungsten copper alloy, so that between the solidifying metal and non-metal solidified to produce a specific temperature gradient, usually resulting in a higher degree of supercooling, so that solidification in a wide range of solubility, the solid obtained phase high content of alloying elements and grain refinement significantly fewer microscopic segregation. Commonly used methods of rapid solidification atomization, melt spinning method and spray deposition.
