| 中文摘要 | Wettability and microstructures of Ni-Al/TiCchi composites have been studied by measuring the wettability contact angle using the "sessile drop" method, and by observation using a scanning electron microscope (SEM) and an analytical transmission electron microscope (ATEM), together with an energy dispersive X-ray spectrometer (EDS). The equilibrium contact angle of Ni-Al alloys on TiCchi (X=0.7-1) vs. Ni content showed that the wetting angle depends on the concentration of C in TiCchi. The results agreed with the observation of morphology at the interfaces between the hard phase skeleton of TiCchi (x= 0.7, 0.9) and metallic phases. The concentration distance plot for Ti, and Ni across the interface of Ni3Al/ TiC0.7 showed that an extensive area of intermetallic compounds can be observed at the Ni3Al / TiC0.7 interface. The microstructure analysis suggested that Ti in TiC0.7 is easier to dissolve into the molten alloy than that in TiC0.9. Some periodic zigzag fringes were also observed in the interface between metallic phase and carbides in the sample of Ni3Al /TiC0.7. The formation of this periodic zigzag fringe, which may be a growth zone of a new Ti-Ni-Al phase, would occur during the initial stage of solidification in the samples obtained by infiltration. This behavior in the interface of Ni-Al/TiCchi composite would affect their strength, creep resistance at elevated temperatures and low-temperature toughness. |
