摘要: In this research an aluminum alloy Al–7Si–0.3 Mg (A356. 1) was cast by a semi-solid casting technique. The parameters like stirring time, temperature and heat treatment conditions on mechanical properties were investigated and obtained optimum conditions. The cylindrical specimens with a height of 40mm and a diameter of 160mm were cast in a permanent mould. Mechanical properties plus fracture surfaces of specimens were identified as brittle or ductile fracture. Results showed that the optimum temperature and time for semi-solid cast …
