Abstract
Disclinations in thin crystals of MgCd alloy are demonstrated by high resolution electron microscopy. The disclinations appear along the intersection lines of twin boundaries which occur due to spontaneous lattice deformations at the phase transition temperature. A star-disclination which is not an intersection line comes out to compensate the strain field of the disclinations. A single disclination is seldom observed but dipoles, tripoles, quadrupoles and multipoles of disclinations are found in stable crystals.
