Abstract
Investigations of the strength and deformability of four types of zirconia-base ceramics stabilized by 9% CeO2 (9Ce — TZP) and having different grain sizes (from 1.4 to 3.0 µm) are described. Under mechanical loads these materials exhibit “avalanche” formation of wide transformation zones. A correlation is established between the special features of the formation of such zones, the deformability of specimens, the the acoustic emission in them, and the grain composition of the material.
