Studies on Long Term Durability of Aluminum Airframe Structure Made by Affordable Process

Abstract

Affordability is one of the most important problems of today's development of airframe especially for aluminum alloy application. Some new aluminum alloys and improved processes are being applied to production cost reduction, and tests related to long term durability of applied structures are also carried out. In this report our recent studies of following three affordable process methods to aluminum alloy structures are introduced, these are outline of process studies and their merits, and mechanical properties, fatigue properties and corrosion resistance. (1)Application of new 6000 series alloy of high formability (2)Application of premium precision casting (3)Application of superplastic forming
