Combined electron microscopy and energy analysis of an internally oxidized Ni + Si alloy

Abstract

The conventional electron microscopy of an internally oxidized 0·05 wt. % Si+Ni alloy is reported. The method of oxidation and the morphology and identity of the precipitates are described. Possible effects of this type of precipitation on the magnetic properties of this and similar alloy systems are briefly considered. Confirmatory evidence for the nature of the precipitates has been obtained by a new technique of combined electron microscopy and energy analysis of the transmitted electrons.
