Abstract
ABSTRACT Al-Sn immiscible alloys possess enhanced tribological properties with increased fatigue strength, which makes them competent among self-lubricating bearing materials. In the present work, a direct chill (DC) casting simulator has been designed and manufactured to cast Al-Sn alloy by forced convection technology. The study embodies two different mechanisms for mechanical forced convection (MFC) by: (i) high shear (HS) rotor-stator device, (ii) conventional stirrer (CS) without stator. Shearing rate of 800 rpm for 60 seconds were kept constant for both the cases. Severe segregation of Sn has been observed in CS-DC cast billet due to prevailed phase separation and gravity sedimentation of Sn-rich phase from Al matrix. However, in the case of HS-DC cast billet uniform distribution of Sn and fine equiaxed grains throughout the volume of the billet has been achieved.
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.
