The Sintering of Iron-Germanium Powder Mixtures

  • G. Cizeron

Abstract

The sintering of mixtures of iron and germanium powders has been studied both as a function of temperature and under isothermal conditions. The atomic percentage of germanium varied between 1.5 and 20 at. %. Several stages were found with formation of either a solid solution or a bi-phase compound; also there is an important porosity formation due to the Smigelskas-Kirkendall effect, which causes perturbations in the shrinkage kinetics. By structural and micrographic study, it was possible to determine the rate of diffusion of each element into the other at each temperature range and also the qualitative and semiquantitative nature of the transitory compounds formed during the sintering.
