Transformation toughening takes place each time a material undergoes tension-induced period transformation. Some ceramics are capable of going through anxiety-induced martensitic transformation, which involves an energy barrier that need to be get over by absorbing energy.[23] Martensitic transformations are diffusionless shear transformations[24] involving the changeover among an "au... https://daltonjgcxe.blogolize.com/nitreto-de-boro-hexagonal-an-overview-78251376
