Transformation toughening happens when a material undergoes worry-induced stage transformation. Some ceramics are effective at 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 "austenite" o... https://magnetic-beads-cell-isola82692.plpwiki.com/7346067/getting_my_techniques_in_ceramics_to_work
