The Effect of Mouldâ€™s Temperature variation on Compressive and Fatigue Properties of Casting Aluminum Alloy
Keywords:Mould, barreling, compressive, fatigue, true strain
The effect of the mouldâ€™s temperature variation on compressive and fatigue properties of a cast Aluminum alloy is explored. The mould pre-heat from the range of 30oC to 200oC that controlled with the aid of the electric oven and the temperature of the mould monitored with the bimetallic galvanometer. The fatigue and compressive properties of the cast Aluminum alloy were experimentally investigated and presented. The results show that the increase in mould temperature was found to increase the true compressive strain and number of cycles to failure (a measure fatigue life). However, stress compressive strength and fatigue limit of the specimen were found decrease with increase in mould temperature. These variation shows that the mechanical properties of cast aluminum alloy can be controlled to suit particular application by varying the sand mould temperature.
