摘要：

Studies for Al-alloys normally employ specimens subject to a fixed solution heat treatment (SHT) and hence the specific role of solutionising is overlooked It is revealed that SHT has a major role in corrosion of AA7150 as judged by electrochemical microscopic and profilometry studies SHT dictates the constituent particle type and population remaining in the alloy for subsequent processing and is thus not only a principal factor in corrosion but a factor that can be engineered in developing more damage tolerant AA7150 Effect of an optimised SHT minimising the residual MgZn(2) and Al(2)MgCu content on corrosion resistance is demonstrated Crown Copyright (C) 2010 Published by Elsevier Ltd All rights reserved
