Research project:?High strength aluminium alloys for aerospace applications

Currently Active:: Yes

Due to their low density and continued improvements in mechanical properties, aluminium alloys have continued to be a key material for aerospace applications.?Research at 天发娱乐棋牌_天发娱乐APP-官网|下载 on these alloys has been led by Profs. Marco J Starink and Ian Sinclair through a series of projects.

Project Overview

Aluminium alloys of the 7xxx (Al-Zn-Mg-Cu), 2x9x (Al-Li), 2xxx (Al-Cu-Mg) and 6xxx classes of alloys are used extensively in aircraft. In collaboration with Airbus, Alcan, Alcoa, Dunlop Aerospace, Cabot Engineering and QinetiQ, these alloys have been studied in a series of projects. The work in 天发娱乐棋牌_天发娱乐APP-官网|下载 has focussed on microstructure-strength relations, strength modelling, embrittlement, quench sensitivity, fatigue and toughness analysis, encompassing all of the major aerospace Al alloy systems. Also welds have been analysed.
