Effect of casting modifiers on surface roughness and chip formation of Al-12Si alloy

ABSTRACT In this study, the effects of casting modifiers on the surface roughness and chip formation of Al-12Si alloy materials were experimentally investigated. Machinability tests were carried out using a conventional lathe. Machinability tests were performed on four different materials, Etial 140, Etial 140 +CuSn5, Etial 140 +Al10Sr and Etial 140 +Al10Sr+CuSn5, respectively. A constant depth of cut, 3 different cutting speeds (Vc: 35, 95, 135 m/min) and three different feed rates (f: 0.08, 0.16, and 0.32 mm/rev) were chosen as test parameters. The most effective roughness reduction under these test conditions was 7.21% for the Al10Sr modified test material. According to the measured density values of the unmodified material, the density values of the other tested materials increased by 1.65% for CuSn5, 0.40% for Al10Sr and 1.16% for CuSn5+Al10Sr. Furthermore, the hardness values increased by 5.48% for CuSn5, 0.58% for Al10Sr, and 15.75% for CuSn5+Al10Sr.

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
