Transformation toughening happens whenever a material undergoes stress-induced period transformation. Some ceramics are capable of undergoing stress-induced martensitic transformation, which consists of an energy barrier that has to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition between an "austenit... https://magnetic-beads-rna-isolat59147.hyperionwiki.com/1931099/what_are_the_properties_of_ceramics_things_to_know_before_you_buy
