Investigation of the Effects of Oxide films on the Mechanical Properties of Al-A356.2 alloy and Simulation of Oxide film Entrapment during the Mold Filling, Ph.D. Dissertation Sharif University of Technology ; Davami, Parviz (Supervisor) ; Varahram, Naser (Co-Advisor)
Abstract
The present study aimed to investigate the effects of old and young oxide films on the mechanical properties and reliability of Cast Al A356.2 alloy. The results indicate that the presence of oxides within the microstructure of the alloy decreased the tensile properties of the alloy and increased their scattering. Beside this, the presence of the oxides decreased the reliability of the alloy. The results showed that the presence of double oxide films (especially old oxides) decreased the Weibull modulus of tensile properties and resulted in bi-Weibull distribution in tensile properties of the alloy. The results also indicate that using of a clean melt (with high quality), is vital for...
