SUBSTRUCTURE EFFECTS UPON DIFFUSIVE TRANSPORT IN METALS.
Abstract
Quantitative measurements were to be made of the rate of diffusive transport of interstitial solute atoms through metals at relatively low temperatures in order to study in detail the possible role of substructure in this process. The experimental studies pursued centered in two areas. The first was the direct measurement of hydrogen permeation through thin samples of palladium and iron at low pressures and temperatures. The second area of study was concerned with the development of microanalysis techniques which could be used to determine microsegregation over small areas, such as near grain boundaries in metals. Here, the emphasis was placed on the application of thin film combined electron probe-electron microscope techniques. A method was developed which allowed for the determination of solute segregation over areas which are smaller than the electron beam size in these instruments. (Author)
