Hot stretch straightening of high strength age hardened metallic form and straightened age hardened metallic form

A method for straightening an age hardened metallic form selected from one of a metal and a metal alloy, comprising:

• heating an age hardened metallic form to a straightening temperature,
• wherein the straightening temperature is in a straightening temperature range from 0.3 of a melting temperature in kelvin (0.3 Tm) of the age hardened metallic form to 25° F. (13.9° C.) below an aging temperature used to harden the age hardened metallic form;
• applying an elongation tensile stress to the age hardened metallic form for a time sufficient to elongate and straighten the age hardened metallic form to provide a straightened age hardened metallic form,
• wherein the elongation stress is at least 20% of a yield stress and not equal to or greater than the yield stress of the age hardened metallic form at the straightening temperature;
• and
• wherein the straightened age hardened metallic form deviates from straight by no greater than 0.125 inch (3.175 mm) over any 5 foot length (152.4 cm) or shorter length;
• and
• cooling the straightened age hardened metallic form while simultaneously applying a cooling tensile stress to the straightened age hardened metallic form,
• wherein the cooling tensile stress is sufficient to balance a thermal cooling stress in the alloy and maintain a deviation from straight of no greater than 0.125 inch (3.175 mm) over any 5 foot length (152.4 cm) or shorter length of the straightened age hardened metallic form.
