| 摘要 |
The invention concerns particularly an alloy in the form of a solid solution of intermetallic compound Ti2AlX, niobium and if necessary additionnal elements capable of forming binary solid solutions with the niobium, X being mainly molybdenum, and Ti2AlX representing 40 to 80 atomic per cent of the alloy. This alloy cristallises with a substantially continuous centered cubic structure giving it excellent mechanical properties over a wide temperature range.
