AbstractIt is well established that titanium alloy structural components will crack when exposed to excessive heat and stress. However, occasionally components are under designed for the application and premature cracking occurs in opterional aircraft. This proposed project is designed to address the issues associated with in-situ crack repair of Ti 6-2-4-6 S components using techniques that will restore near parent material microstructures and mechanical properties to the repaired area. Low temperature metal deposition techniques will be demonstrated to replace lost material in the area of the crack. Local heat treat approaches will be applied to the repair area to minimize rsidual stresses. Solid state weld repairs will be demonstrated using techniques that will enable in-situ repair procedures and evaluated to demonstrate the feasibility of the repair to retain near parent metal properties and microstructure.
