Title:
ALUMINUM ALLOY MATERIAL AND ALUMINUM ALLOY STRUCTURE AND PRODUCTION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/080650
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an aluminum alloy material which is useful in various aluminum alloy structures and which can be joined even in the form of a single layer and does not suffer from a shape change before and after the joining. The problem can be resolved by an aluminum alloy material which contains 1 to 5 mass% of Si and 0.01 to 2.0 mass% of Fe with the balance being Al and unavoidable impurities and in which Si-based intermetallic compound particles having equivalent circle diameters of 0.5 to 5μm are present in the section in an amount of 250 to 7×105 particles/mm2, while Al-based intermetallic compound particles having equivalent circle diameters of 0.5 to 5μm are present therein in an amount of 100 to 7×105 particles/mm2. This aluminum alloy structure can be produced by joining in a vacuum or a non-oxidizing atmosphere at a temperature such that the mass ratio of a liquid phase formed in the aluminum alloy material at the temperature to the aluminum alloy material falls in the range of 5 to 35%.
