Transformation toughening occurs when a material undergoes strain-induced stage transformation. Some ceramics are effective at undergoing worry-induced martensitic transformation, which will involve an energy barrier that have to be overcome by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover between an "austenite" ... https://magbeads25791.thecomputerwiki.com/6140424/the_fact_about_silicon_nitride_ceramic_that_no_one_is_suggesting
