Abstract |
|
In this work the microstructure and mechanical properties were studied on Al7075 alloy with the tin addition as the alloying element in a cast condition. 5% tin was added in Al7075 alloy to study the characteristic changes. The alloy was casted by die casting process in the foundry in required shape. After stir casting, the samples are age hardened and analysed for structural, mechanical and corrosion behaviour. The formed intermetallic compounds (Al₃Cuâ‚â‚‚Sn) retards the grain growth, lead to grain refinement and result in further strengthening effect. The incremental increase in the strength of the cast sample is due to the precipitation hardening and orowan strengthening which are working together. The outcome of this process indicate, that the mechanical strength and Corrosion resistance have been enhanced much better than the parent material. |
