We investigated transformation of 4H-SiC etching shapes by high temperature annealing. Although the etching mask was circular, the etched shape resulted in a hexagon, dodecagon, or octadecagon, depending on the etching area size. A hexagon was transf

Recently, the improvement of the high strength of fine grain steels has been investigated actively. Fine grained steels have high yield stress, as expected by the Hall-Petch relationship. Therefore, these materials are considered for use as structura
