Abstract
A sheet of Ti 6-2-2-2-2 alloy having a starting thickness of between approximately 0.040 inches and 0.187 inches is thermomechanically treated at a temperature of between approximately 1500 degrees F. and 1750 degrees F. at a mechanical strain rate in the range of between approximately 1.times.10.sup.-4 and 1.times.10.sup.-2 inch per inch per second to produce a formed part having a tensile strength which is approximately 33% greater than untreated rolled Ti 6-2-2-2-2 alloy sheet or plate.
