In this present work, the effect of tin additions was studied on age hardening behaviour of AZ92 magnesium base alloy by hardness and metallographic measurements. For this, three alloys, AZ92, AZ92+ Sn (3%) and AZ92+ Sn (6%) were produced by the sand casting process in the foundry. In tin containing alloys, the tin is added in AZ92 alloys by an amount, 3% and 6% respectively. Samples of these alloys were solution treated at 400ºC for 24 hrs and subsequently aged at 150ºC, 200ºC and 250ºC for various times and ageing plots were obtained by Rockwell hardness measurements. Further Microstructure and XRD analysis were carried out on samples in peak aged condition. The hardness in all these cases increased to peak value.
