Abstract Scope |
The mechanical behaviour of two-dimensional micro-lattices fabricated from <100> oriented single crystal Ni samples was studied using in situ micromechanical testing device inside a scanning electron microscope. Three different samples were tested, two with regular hexagonal holes, and one with round holes, all samples having equal hole area fraction. The two sets of samples with hexagonal holes had the hexagons oriented at 0° and 30° with respect to the tensile axis, while the sample with round holes had the holes oriented at 0°. The tensile strength of the sample with hexagonal holes oriented at 0° was higher than the one oriented at 30°, and it had a considerably lower ductility. However, the sample with circular holes at 0° orientation had a tensile strength and ductility similar to that of the hexagonal 0° sample. Thus, it was seen that hole orientation was more important in determining the properties than hole shape. |
