Transformation toughening occurs any time a material undergoes pressure-induced phase transformation. Some ceramics are able to undergoing pressure-induced martensitic transformation, which requires an energy barrier that needs to be defeat by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover amongst an "austenite" o... https://silicacoatedmagneticbeads26936.blognody.com/45918219/top-what-is-ceramic-made-of-secrets
