Theory of inclusion controlled grain growth

  • N. A. Haroun

Abstract

Different inclusion/grain boundary interactions have been analysed with emphasis on the grain boundary structure and the geometry of the inclusion/boundary profiles. Crystalline inclusions can inhibit grain growth, provided one or more inclusions intersect each boundary. An equation for the limiting grain size, in terms of the volume fraction and the particle size distribution of the inclusions, is derived and is shown to explain the inclusion controlled limiting grain sizes in calcium fluoride and in alumina, as well as grain coarsening in steel. Conditions for the drag of amorphous particles or pores, and for pore isolation are discussed.
