Transformation toughening occurs when a material undergoes stress-induced phase transformation. Some ceramics are effective at going through strain-induced martensitic transformation, which will involve an energy barrier that needs to be triumph over by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover between an "au... https://daltonopobb.daneblogger.com/37973228/the-boron-nitride-uk-diaries
