Squeeze Casting-Influence of Squeeze pressures on Das and other related properties
2013
Squeeze casting is a hybrid process combining the advantage of both casting and forging. It is established that squeezed casting technique improves the properties of the castings. Dentritic arm spacing has profound influence on all the mechanical properties of material like hardness, tensile strength, ductility and toughness. Dentritic arm spacing is the distance between the adjoining arms of dendrites. In this study, Al-Si-Cu alloy (LM4) has been considered and cast at various squeeze pressures. Toughness test, hardness test, ultimate tensile strength test and DAS values were conducted on the obtained castings. It was noted that mechanical properties increase or decrease corresponding to DAS values.
