Systematics of the cellular precipitation reactions

  • Erhard Hornbogen
Symposium on the Cellular and Pearlite Reactions

Abstract

A systematic description is given of cellular reactions with special account to the discontinuous precipitation. The following special aspects of this reaction are discussed: The constitutional, nucleation, and other conditions for its occurrence; the role of grain boundaries, dislocations, and vacancies for the mechanism; the effect of continuous precipitation before discontinuous precipitation; multiple discontinuous reactions; effects of grain boundary structure, third elements, and external stress; reactions in highly defect crystals and amorphous solids. It is shown that all phenomena can be understood either by effects on driving force or mobility of the reaction front.
