Transformation toughening occurs every time a material undergoes pressure-induced phase transformation. Some ceramics are able to undergoing pressure-induced martensitic transformation, which entails 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" ... https://viral-rna-extraction-kits03570.ageeksblog.com/37736200/helping-the-others-realize-the-advantages-of-how-does-a-ceramic-heater-work
