Method for improving aging response and uniformity in beta-titanium alloys |
摘要 |
The invention relates to a process for improving the aging response and uniformity in a beta titanium alloy comprising the steps of: (a) cold working said beta titanium alloy to at least about 5% so that a reasonable degree of recrystallization can be obtained during subsequent solution treatment; (b) pre-aging said cold worked alloy at about 900 DEG to about 1300 DEG F. for a time in excess of about 5 minutes to obtain a pre-aged alloy; (c) solution treating said pre-aged alloy at a time and temperature to achieve a reasonable degree of recrystallization of said pre-aged alloy above the beta transus; and (d) aging said solution treated alloy at temperature and times to achieve a pre-aged, solution treated and aged beta titanium alloy substantially in a state of metallurgical equilibrium.
