摘要: Light alloys, and aluminium alloys in particular, are widely used to model new processes their association with the aerospace industries often places them at forefront of emerging technologies. Moreover, knowledge microstructure/property relationships is providing opportunities design meet specific service requirements. These two themes as basis for discussing recent developments aluminium, magnesium titanium alloys. Particular attention given ageing practices, lithium-containing role trace elements controlling precipitation aluminides. Reference also made several materials produced by unconventional methods processing.
