Transformation toughening occurs any time a material undergoes strain-induced stage transformation. Some ceramics are effective at undergoing strain-induced martensitic transformation, which entails an energy barrier that needs to be defeat by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition among an "austenite" or ... https://silica-magnetic-beads48035.targetblogs.com/39558689/what-does-aluminum-nitride-pcb-mean
