Tough, high-strength titanium alloys; methods of heat treating titanium alloys |
摘要 |
The present disclosure describes methods of heat treating Ti-based alloys and various improvements that can be realized using such heat treatments. In one exemplary implementation, the invention provides a method of forming a metal member that involves forming an alloy into a utile shape and cooling the alloy from a first temperature above a beta transus temperature of the alloy to a second temperature below the beta transus temperature at a cooling rate of no more than about 30° F./minute. If so desired, the alloy my be treated for a period of about 1-12 hours at about 700-1100° F. Titanium alloys treated according to aspects of the invention may have higher tensile strengths and higher fracture toughness than conventional wrought, mill-annealed Ti 64 alloy. |
