Effects of interstitial impurities on phase equilibria

  • Published:
Bulletin of Alloy Phase Diagrams

Abstract

Because interstitial elements are ubiquitous in the environment, it is inevitable that they will be present as contaminants in most metals unless unusual precautions are taken in preparing and/or handling them. Data are available which show that the common interstitial elements (oxygen, nitrogen, carbon, and hydrogen) interact with most metals to modify both the electron distributions and the vibrational behavior. A small amount of an interstitial impurity can have a drastic effect on the position of the phase boundaries of an equilibrium diagram, the stability of a phase, the allotropic behavior of a metal, and the melting point of a metal.
