On the use of Positron Annihilation Spectroscopy in the Study of a Nonuniform Spatial Distribution of Metallurgical Defects

  • James P. Schaffer (a1)

Abstract

Most of the Interpretation of positron annihilation results to date have been done within the context of the simple trapping model which assumes a uniform spatial distribution of defects within the specimen examined. While this assumption is often justifiable there are numerous metallurgical defect configurations which are markedly nonuniform. In this work some of the appropriate trapping models which have previously appeared in the literature will be briefly reviewed. Additional models which are currently being developed will be presented and the series of experiments which are being used to test the trapping models will be described.
