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.

为了开发高性能的热电材料，实验研究了在铋和钙基层状钴矿中形成(001)织构的方法。为此，研究了高温压缩变形。(001)面上的相邻原子与层状钴矿中的原子相同，因此推测(001)面可能是滑移面，导致单轴压缩变形形成(001)面(压缩面)织构。证实了在高温、低应变率下进行压缩变形时，织构形成。
