Abstract : An axial extension that takes place during cyclic torsion over a large number of cycles is known as the Ronay effect. In a directionally solidified eutectic of solid cross section, the tendency for the surface layers to elongate during cyclic tension is resisted by the interior with the result that elastic buckling of the fibers in the surface layers occurs. An explanation for this type of effect is advanced which is based upon the elastic distortion of the lattice and the anisotropy of the slip process in the matrix. (Author)
