I am curious to see what people are using for replacement tires on the new FGT(or GT350-R)? For those who have gone through a set of the Cup 2's, did you all go back to them or get something more durable/streetable for regular non tract use? Is there a tire that is good for both the tract and...
Damn, those look good! Wish I'd seen them before I sprung for a set of factory alloy wheels (as a street alternative to my carbon fiber wheels). Reasonably priced, too!
Its been 30 years since my Materials Science class, but the process is called annealing and it reduces the strength of alloys.
Annealing may be required either prior to or intermittently during forming operations in order to relieve strains or to reduce the strength of alloys in age-hardened tempers. The aim is usually to improve workability for subsequent manufacturing operations, but annealing may also be directed toward the development of a desired size and distribution of precipitates for grain structure control and to control the size of primary phases that form at the working temperature. The specific annealing treatment depends on the alloyand the structure developed during prior thermal and mechanical operations.
Annealing temperatures are usually in the range 615–690 K, with holding times from a few minutes to a few hours. When annealing previously cold-worked products care must be taken to prevent undesired recrystallization and grain growth in critically strained regions. Heating and cooling rates must be controlled to avoid precipitation-hardening in heat-treatable alloys. However, annealing operations are also used to precipitateequilibrium phases in special thermomechanical processing treatments directed toward grain refinement. The treatments include severe overaging, deformation, and recrystallization steps. A critical relationship exists between the precipitate size and distribution developed during the anneal given prior to working, and the recrystallized grain size developed during the anneal after deformation.
