Abstract
Methods for the manufacture of the above-mentioned titanium alloy for use in combustion engine exhaust systems are disclosed herein. An exemplary method of the disclosed subject matter for the manufacture of titanium alloy for use in a high temperature and high stress environment includes performing a first heat treatment of the titanium alloy at a first temperature, rolling the titanium alloy to a desired thickness, performing a second heat treatment of the titanium alloy at a second temperature, and performing a third heat treatment of the titanium alloy at a third temperature. In some embodiments, the first temperature is selected such that recrystallization and softening of the titanium alloy is optimized without substantial coarsening of second phase particles and can be approximately 1500-1600° F. In some embodiments, the rolling of the titanium alloy reduces the thickness of the titanium alloy by at least than 65%.
