摘要：
In situ observation under TEM was made of the dynamic process of martensitic transformation in (Y,Mg)-PSZ ceramics. A group of substructural martensite variants may occur priorly under the contact stress between tetragonal ZrO2 precipitates, the another one may be induced by the elastic strain relaxation and both form (100) twins. The crystallographic aspect of the martensitic transformation was also discussed.
