Available 3D data of the intermetallic obtained with focused dual ion beam tomography were used to simulate the deformation behavior. The modeling revealed a high structural compliance akin to the bending-dominated behavior of cellular solids. The high compliance suggests that the microstructure is able to reinforce the alloy without compromising the ductility, for strains above 1%. The interconnected network adds some 7 MPa to the total strength of the alloy.
