Transformation toughening occurs any time 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 concerning an "austen... https://magbeads50369.ltfblog.com/37777210/si3n4-insulating-ring-brands-no-further-a-mystery
