Controlling Grain Growth

Part of the Materials Science Research book series (MSR, volume 21)

Abstract

A thermodynamic view is taken to explain how inclusions and lattice strains (developed when adjacent grains have slightly different lattice parameters) can be used to control grain growth in advanced ceramics. Experimental data are presented for the cases where A12O3 inclusions are used to inhibit normal grain growth in cubic ZrO2, ZrO2 inclusions inhibit abnormal grain growth of A12O3 and, compositional differences between adjacent grains, developed during slow partitioning, dramatically inhibit grain growth for compositions fabricated in the two-phase region of the ZrO2-Y2O3 system.
