| Research Abstract |
In order to develop a high performance thermoelectric materials, the method to develop a (001) texture in Bi and Ca based layered cobaltites is experimentally examined. For this purpose, high temperature compression deformation was examined. The neighboring atoms on (001) are the same atoms in layered cobaltites, hence it is expected that (001) might be a slip plane, resulting in the formation of (001) (compression plane) texture by the uniaxial compression deformation. It is confirmed that the texture develops when the compression deformation is conducted at high temperatures with low strain rates.
