Transformation toughening occurs any time a material undergoes pressure-induced phase transformation. Some ceramics are able to undergoing strain-induced martensitic transformation, which will involve an energy barrier that have to be conquer by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover in between an "austeni... https://rna-beads69258.wikiinside.com/3277311/the_fact_about_silicon_nitride_ceramic_that_no_one_is_suggesting
