摘要：
The in situ TiB/Ti-4.0Fe-7.3Mo composites were fabricated by plasma spark sintering (SPS) technique using mechanical alloying of Ti, Fe65Mo and B powder. The effects of sintering temperature on densification of the composites and microstructure of the in situ synthesized TiB were investigated using scanning electron microscope (SEM) and transmission electron microscope (TEM). A dense composite was obtained after sintering at 1000degreesC for 5 min. Under proper ball milling and SPS conditions in situ TiB reinforced Ti-4.0Fe-7.3Mo composites have been prepared. The in situ TiB showed a typical needle shape grow along [010] direction. The transverse cross-section of TiB grain is a hexagonal shape with the planes of (100), (101) and (101). The stacking faults in the (100) plane were observed in the TiB needles. (C) 2004 Elsevier B.V. All rights reserved.
