A method for X-ray determination of elastic constants of multiphase materials for the use in the practice

The basic calculations were already carried out by Hauk et al. This paper now gives formulas and graphical representations for practical application by which the elastic constants of multi-phase materials can be determined quickly and without greater mathematical effort. The elastic constants of the pure phases, calculated from the monocrystal coefficients according to Bollenrath, Hauk and Mueller, and the mechanical elastic constants are assumed to be already known. Sintered and molten materials, fibrous materials, and materials in sandwich structure are considered separately. (orig./RW)
