|Title:||Blackman Diagrams and Elastic-Constant Systematics|
|Published:||January 05, 2001|
|Abstract:||We consider Blackman diagrams for various cubic materials. These diagrams, plots of reduced elastic-stiffness coefficients C12/C11 versus C44/C11, show that materials with similar chemical bonding tend to fall in the same region of the diagrams. Such diagrams provide many uses. One important use is to enable determination of the complete cubic-symmetry Cij-Cd11^, C12, C44-from the quasiisotropic (polycrystal) elastic constants. The diagram gives information about elastic anisotropy, departures from central interatomic forces, and lattice instabilities, Examples considered include b.c.c. metals, f.c.c. metals, diamond-cubic elements, alkali halides, oxides, 8-N compounds, carbides, semiconductors, and Fe-Cr-Ni alloys (austenitic stainless steels).|
