PROPAGATION OF ELASTIC-WAVES IN EQUIAXED STAINLESS-STEEL POLYCRYSTALSWITH ALIGNED [001] AXES

The unified theory for elastic wave propagation in polycrystalline mat erials, developed by Stanke and Kino [J. Acoust. Sec. Am. 75,665-681 ( 1984)], has been applied to compute the propagation constants in mater ials consisting of cubic crystallites with texture. The particular tex ture considered here is one in which one of the cube axes of each crys tallite is aligned in a preferred direction with the other two being r andomly oriented, leading to a material with macroscopic transverse is otropy. The calculations are done for plane waves under the assumption that the single crystal anisotropy is not large. Numerical results fo r the variations of attenuation and phase velocity with direction of p ropagation and frequency are presented for L, SH, and SV waves. (C) 19 96 Acoustical Society of America.
