Existence of enhanced solid state diffusion during mechanical alloying of Si and Ge

Abstract

Silicon-germanium was mechanically alloyed in a high energy planetary ball mill and the microstructural development of the solid solution investigated. X-ray diffraction and transmission electron microscopy revealed that alloy formation is accomplished by a solid state diffusion process which is enhanced by the creation of defects and strain during the milling process.© 1995 American Institute of Physics.
