ADVANCED SHEET METAL FORMING OF ALUMINUM ALLOYS

摘要

The review describes recent researches and developments made on various kinds of aluminum alloy sheets. Three subjects will be given independently but all contribute to advanced forming technology on the alloys simultaneously. The object of the paper is described as follows: (l) To demonstrate characteristic serrated flow behavior in Al-Mg alloys in wide range of strain ratio. (2) To show the good quality and the feasibility of pre-coated Al sheets developed recently. (3) To introduce revised superplastic blow forming techniques for super-plastic Al alloys by using gas generant.
