PRECISION MACHINING AND HIGH EFFICIENCY HEAT TREATMENT OF ALUMINUM

摘要

The present invention relates to a processing and a heat treatment method of aluminum. The present invention is able to minimize strain energy accumulated inside a raw material due to cold working before solution treatment and to minimize the number of crystal grains to be recrystallized, thereby making crystal as large as possible. The present invention slows down a rate of stress corrosion cracking, lessening crack fracture, for extending service life of raw materials.;COPYRIGHT KIPO 2019
