INTWERNATIONAL PATENT CALENDAR METALLURGY OF ALUMINUM ALLOY HEAT TREATMENT

摘要

The quest for higher strength materials, especially in transportation markets, seems to be never ending. The aluminum industry is meeting the demand with new alloys and heat treatments aimed at optimizing properties made of age hardening aluminum. Processing age hardening aluminum alloys to meet high strength levels in various product forms requires special heat treatment, i.e., control of temperature and time in heating and cooling as well as possible deformation at every stage of production, from cast ingot to finished product. As the patent survey presented here centers around heat treatment of aluminum alloys, more specifically on the metallurgy of age hardening aluminum alloys, it is seen that recent inventions in this field apply across the spectrum -from castings to extrusions, forgings, sheet and plate, and wire products in all aluminum market applications.
