Transformation toughening happens any time a material undergoes stress-induced phase transformation. Some ceramics are able to undergoing strain-induced martensitic transformation, which consists of an energy barrier that have to be conquer by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover amongst an "austenite" o... https://jaidengiged.vidublog.com/37996140/the-boron-nitride-uk-diaries
