Abstract
This paper attempts to present, by means of a succession of micrographs, a literal picture of a portion of the diffusion process occurring in iron-silicon powder compacts. It discusses the metallographic characteristics of Fe-Si alloys (especially in the 6 pct Si range), compounded by the powder process, and describes various misleading pseudomorphic structures encountered in microscopic investigation. An etch is described which indicates Si content within certain rather wide ranges.
