| Outline of Final Research Achievements |
Recently, we have found that the high temperature strength of transition-metal silicide-based directionally solidified (DS) eutectic composites can be improved drastically when the transition-metal element in the composites is substituted by large amounts of two or three different transition-metal elements simultaneously. In this study, deformation mechanisms of various component transition-metal silicide phases in the eutectic composites as well as the proper growth conditions for obtaining DS eutectic composites with homogeneous and fine lamellar microstructure were investigated in order to elucidate the strengthening mechanisms of the DS eutectic composites.
