Transformation Toughening happens any time a material undergoes anxiety-induced period transformation. Some ceramics are effective at going through worry-induced martensitic transformation, which requires an energy barrier that need to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover between an "auste... https://rowaneffda.wikienlightenment.com/8283102/what_does_aluminum_nitride_pcb_mean
