Abstract : 319 type aluminium alloy is a high strength heat treatable alloy having wide range of engineering ap plications. The most
common chemical treatment consists of mo difying the morphology of silicon eutectic phase from acicular to fibrous form, thus
improving the mechanical properties. The basic properties of this alloy can be improved by the prope r choice of melt treatments
such as grain refinement and modification followed by precipitation hardening treatment at optimum heat treatment condition of
temperature and time. The present study envisages optimizing the ageing condition of 319 alloy. The melt treatment involves grain
refinement with Ti-B master alloy and modification with Al- Sr master alloy. The alloy cast in permanent mould is machined to
make samples for evaluation of mechanical properties and metallographic studies. The machined samples were subjected to
solution treatment at a constant temperature of 500°C and aged at different temperatures. The effect of ageing on
microstructure will be discussed
