| Abstract: | Samples of ZL205A alloy were prepared by counter-pressure casting process.Mechanical property,microstructure and fracture morphology of the samples were analyzed.The results show that comparing with the same alloy by low-pressure casting and gravity casting,tensile strength and elongation of ZL205A alloy by counter-pressure casting are higher.Moreover,the microstructure is finer and free of casting defects of porosity,and its fracture exhibits ductile fracture characteristic. |
