Abstract
A method for forming a structure using an interim temper process is provided. A metal material is partially-aged to a stable temper that does not require cold storage. The partially-aging step is completed at a supplier facility prior to the metal material being received by the manufacturer. Once received by the manufacturer, the partially-aged metal material is heated to a first temperature to perform retrogression. A structure is formed from the partially-aged metal material after performing the retrogression. The structure is shaped and inspected. The structure is then heated to a second temperature in an age oven to reach its final aged state. The final aged state may be close to, meet, or exceed a T6 temper.
