Plastic Deformation Behavior of Al-Si Alloy
Al-Si 합금의 소성변형 거동
Abstract
The effect of microstructural characteristics of A356 alloys on tensile behavior was studied ill the present study. To authors' knowledge, the microstructural effect on mechanical properties of A356 alloy has not been well understood even though this alloy system is one of the most widely used alloys for the industrial purpose. Specially, quantitative relationship between properties like ductility and fracture toughness with microstructural features is lacking. In the present study, three processing routes was used to fabricate samples with different microstructures like size and distribution of primary alpha and eutectic phases. Also, compressive deformation was used to close casting porosity for the cast samples. Tensile behavior was examine and discussed in terms of microstructural aspects.
