Effect of Al2O3 Nano Particle Addition on Mechanical Properties and Creep Behaviour of High Pressure Die Cast AZ91-1Sr Alloy
ABSTRACT The AZ91-1Sr alloy, the 0.5, 1 and 2 vol.% Al2O3/AZ91-1Sr nanocomposites were fabricated by high pressure die casting method and investigated the effect of nano Al2O3 particles on the mechanical properties and creep behaviour of the AZ91-1Sr alloy. Mechanical and creep tests disclosed remarkable enhancements in the yield strength, tensile strength, hardness and creep resistance of the AZ91-1Sr alloy with addition of nano Al2O3 particles. The best results were obtained in the case of the addition of 2 vol.% Al2O3 nano particles.
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.
