A dynamic process of the martensitic transformation in(Y,Mg)-PSZ ceramics was observed in situ using TEM.Under the effect of contact stress between tetragonal(t)-ZrO_2 precipi- tates,a group of substructural martensite variants may occur priorly and then another one was induced by the elastic strain relaxation,both form(100)_m twins further.In addition,the crystallography of the martensitic transformation was also discussed.
