Transformation toughening takes place whenever a material undergoes stress-induced period transformation. Some ceramics are capable of going through tension-induced martensitic transformation, which involves an energy barrier that have to be conquer by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover amongst an "aus... https://silica-magnetic-beads48035.targetblogs.com/39558689/what-does-aluminum-nitride-pcb-mean
