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 needs to be defeat by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the transition amongst an "austenite" or ... https://isolation-of-trace-dna19517.azuria-wiki.com/2014733/a_secret_weapon_for_silicon_carbide_ceramic_columns
