A method for heat-treating a titanium alloy, such as Ti-6Al-4V. The method may occur after or include a step of forging the titanium alloy such that localized, highly deformed grains are formed in the titanium alloy. Then the method may include steps of recrystallization annealing the titanium alloy by heating the titanium alloy to a temperature in a range between 30&#xb0; F. to 200&#xb0; F. below beta transus of the titanium alloy for 1 hour to 6 hours and then furnace cooling of the titanium alloy to 1200&#xb0; F. to 1500&#xb0; F. at a rate of 50&#xb0; F. to 500&#xb0; F. per hour. Following the recrystallization annealing, the method may include beta annealing the titanium alloy. These steps may be performed in a single heat treating cycle.

An aircraft thrust reverser inner wall and method of manufacturing the same. The aircraft thrust reverser inner wall may include a face sheet, a perforated back sheet, and a core sandwiched between the face sheet and the perforated back sheet. The face sheet may have an inner face sheet surface and an outer face sheet surface, and the core may have an inner core surface, an outer core surface, and a plurality of cell walls extending therebetween. An electro-depositable material may be applied, via electrodeposition, in a substantially continuous layer over the outer core surface, the cell walls, and the outer face sheet surface, thus bonding the face sheet and core together. The perforated back sheet may be attached to the core at the outer core surface, and a conductive coating may be applied to the inner face sheet surface.
