Transformation toughening happens whenever a material undergoes stress-induced stage transformation. Some ceramics are effective at undergoing stress-induced martensitic transformation, which consists of an energy barrier that has to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition between an "austeni... https://lysis-buffer-for-rna-extr72592.webbuzzfeed.com/39578592/the-best-side-of-advanced-ceramics-products
