Transformation Toughening occurs when a material undergoes strain-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://silicamagneticbeads37046.wikiconversation.com/7809589/top_latest_five_ceramic_alumina_urban_news
