| Abstract | The effects of oxygen on the microstructure of Ti47Al0.7B (at. pct) alloy for as-cast automotive valves were investigated. Six alloys with oxygen content from 0.4 to 1.4 at. pct were prepared by induction melting and centrifugal casting in CaO crucible under protective atmosphere. The microstructures were observed by optical microscopy (OM) and scanning electron microscope (SEM). The results show that the increase of oxygen content led to grain refinement and enhanced the microhardness as well as the α2 volume fraction in the TiAl-based alloys. ©2010 by The Editorial Board of Journal of Materials Science & Technology. |
