摘要
研究退火态Ti_2AlNb合金热轧板材在温度为940～980℃和初始应变速率为8.33×10^(-4)～1×10^(-2)s^(-1)时的超塑变形行为。结果表明:该合金具有良好的超塑性;在本实验范围内,其最高伸长率可达400%,最佳超塑条件为960℃和1.67×10^(-3)s^(-1),可用作超塑性成形工艺制作复杂构件。
The superplastic behavior of annealed Ti2AlNb based alloy sheets was investigated at temperature range of 940-980 ℃ and initiate strain rate range of 8.33×10^-4-1×10^-2 s^-1. The results show that the alloy exhibits good superplasticity. The maximum tensile elongation can reach up 400% at the temperature of 960 ℃ and the initiate strain rate of 1.67 × 10^-3 s^-1. Some complex parts will be formed by superplastic forming technology.
