Transformation Toughening occurs any time a material undergoes pressure-induced phase transformation. Some ceramics are able to undergoing strain-induced martensitic transformation, which requires an energy barrier that must be prevail over by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition involving an "austenite"... https://mylesjjjhf.popup-blog.com/37982107/what-does-aluminum-nitride-pcb-mean
