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 need to be get over by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover in between... https://zanezzxur.wikinarration.com/7394165/top_latest_five_ceramic_alumina_urban_news
