| Abstract: | The precipitating behavior of Ti,involving the formation and effect of brittle sheath film of (Ti,Mo)C,at the crystal boundary of a high temperature alloy with large crystal grain size was observed by the means of extraction carbon replica technique on the grain surface,the influences of different amount of Nb were studied on the composition,amount,morphology distribution and precipitating phase type at the crystal boundaries.The direct and indirect actions caused by elements W and Mo to the precipitating behaviors of carbides and borides at the boundary were discussed. |
