Abstract

A rapid solidification rate (RSR) route aluminium alloy contains lithium and a dispersoid forming ingredient selected from niobium, molybdenum, hafnium, tantalum and tungsten. These dispersoid forming ingredients resist coarsening in the matrix at solution treatment and ageing temperatures. The dispersoid forming ingredient is preferably present in 0.2 to 5.0 percent by weight.
