Shear-induced structural transformation and plasticity in ultraincompressible ReB2 limit its hardness
The recent search for superhard materials concentrated on diborides of the 5d transition metals because of their high elastic moduli. Using density-functional theory we report a systematic study of the shear-induced irreversible structural transformations and plasticity in ReB(subscript 2) which lim...
