The workability of 'XD' titanium aluminide alloys with low volume fractions of TiB2
- 1. Wright State University, Dayton, OH (United States)
Description
A determination is made of the effect of lowering the volume fraction of titanium diboride on the workability of the Ti-48Al-2Mn-2Nb titanium aluminide alloy. It is found that the workability of the low-TiB2 alloys is similar to that of alloys containing 7.5 TiB2; the improved workability of these alloys is accordingly considered to be due to the control of grain size that is achieved by the dispersion of a hard stable phase. While a volume fraction of 0.5 percent was insufficient for consistent retention of fine grain size, alloys with 1-2 vol pct TiB2 deformed uniformly at high temperatures. 6 refs
