Transformation toughening occurs every time a material undergoes pressure-induced phase transformation. Some ceramics are able to going through pressure-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 changeover among an "austenite"... https://tracednaextractionandpuri60370.kylieblog.com/39773203/not-known-details-about-aln
