| 英文摘要 | The effects of B and C on the macro- and micro-structures of near gamma TiAl alloys were compared. The results show that fine equiaxed grains are obtained with increasing concentration of B or C, but grain refinement by the two alloying additions exhibits different features. The grain size of the B containing alloy decreases gradually with increasing B content, whereas for alloying with C, the grain size drops suddenly beyond a critical C content. Microscope observations reveal that even trace lavel of B triggers the formation of TiB2-type boride which exhibits different morphologies with increasing B content. In alloys containing C, carbide particles can not be observed under optical microscope beneath the critical level of C, but large amounts of carbide particles are seen once the critical concentration is reached. The carbide is predominantly Ti2AlC as identified by electron diffraction. A brief analysis was made of the grain refining effects by B and C. |
