Transformation toughening takes place whenever a material undergoes stress-induced period transformation. Some ceramics are capable of going through tension-induced martensitic transformation, which will involve an energy barrier that have to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover between an... https://charlieayrok.blogrelation.com/45714725/ceramicos-propiedades-for-dummies
