Microstructural and phase transformations during the preparation of Ni-Ge solid solutions by mechanical alloying

Data are presented on the mechanically activated formation of solid solutio ns in the Ni-Ge system, where the constituent metals differ sharply in mech anical properties. X-ray diffraction and electron microscopy examination re veals successive formation of layered composites, intermetallic compounds, and fine-particle solid solutions with a highly disordered structure.
