Tungsten Copper Electrode Powder Direct Sintering II

Mechanical alloying powder is different from casting metal or alloy material, its atoms coupling tightly and come into being solid solution or compounds. In general, Milling in a limited time only make contact at those points, lines and surfaces at or approaching the atomic distance of each component, and end up with a very uniform distribution of each component of a mixture or compound.

The principle is that extruding, crushing, welding, re-extruding and forming composite grains in the beginning of milling. And composite grains will emerge new atom surface, layered structure refine under the mechanical force. In the process of mechanical alloying, layered structure forming is a symbol of the beginning of elements alloying, which shortens the diffusion path of solid state atoms and accelerates tungsten copper alloying process. In addition, the larger lattice dislocation density, which in turn provides a fast diffusion path for the alloying proceeds, the alloy further accelerates the process.
