Processing of α+β titanium alloys |
摘要 |
Processes for forming an article from an α+β titanium alloy are disclosed. The α+β titanium alloy includes, in weight percentages, from 2.90 to 5.00 aluminum, from 2.00 to 3.00 vanadium, from 0.40 to 2.00 iron, and from 0.10 to 0.30 oxygen. The α+β titanium alloy is cold worked at a temperature in the range of ambient temperature to 500° F., and then aged at a temperature in the range of 700° F. to 1200° F. |

1. A process for forming an article from an α+β titanium alloy comprising:
cold working the α+β titanium alloy at a temperature in the range of ambient temperature to 500° F.; and direct aging the cold-worked α+β titanium alloy at a temperature in the range of 700° F. to 1200° F.; the α+β titanium alloy comprising, in weight percentages, from 2.90 to 5.00 aluminum, from 2.00 to 3.00 vanadium, from 0.40 to 2.00 iron, from 0.10 to 0.30 oxygen, titanium, and incidental impurities; and wherein the cold working and direct aging forms an α+β titanium alloy article having an ultimate tensile strength in the range of 155 ksi to 200 ksi and an elongation in the range of 8% to 20%, at ambient temperature. |
