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 have to be conquer by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover in between ... https://augustkicxr.yourkwikimage.com/2062434/everything_about_aluminium_nitride_sputtering_target_disc
