Microstructural evolution during partial remelting of AM60B magnesium alloy refined by MgCO3 CHEN Ti-jun(陈体军), MA Ying(马 颖), WANG Rui-quan(王瑞全), LI Yuan-dong(李元东), HAO Yuan(郝 远) Key... by MgCO3 and its microstructural evolution was investigated during partial remelting. The results indicate that MgCO3 is an effective grain refiner for AM60B alloy and can decrease the grain size from......
Partial Remelting of Thixotropic Magnesium-Rare Earth Alloy from Near Non- Equilibrium- Liquidus Casting Cui Jianzhong1,Le Qichi1,Xu Baoqin1,Wang Zhongjun1 (1.Key Laboratory of Electromagnetic Processing of Materials, Ministry of Education, Northeastern University,Shenyang 110004, China) Abstract:After the investigation on partial remelting of thixotropic magnesium serial alloys (ZK60) by near......
Microstructural Evolution during Partial Remelting of Al-Si Alloys Containing Different Amounts of MagnesiumA.Abedi1,M.Shahmiri2,B.Amir Esgandari2,B.Nami11. Department of Mechanical Engineering... partial remelting at semi-solid temperature decreased by adding magnesium,probably due to the decrease of both the solide liquid interfacial energy and inter-diffusion coefficient of solute atoms.关......
Microstructure Evolution and Grain Coarsening Behaviour During Partial Remelting of Cyclic Extrusion Compression Formed AZ61 Magnesium AlloyChangpeng WANG,Huasheng MEI,Rongqiang LI,Difan LI,Ling WANG... evolution and grain coarsening behaviour of AZ61 magnesium alloy produced by the recrystallisation and partialmelting (RAP) process were investigated. Before partial remelting, as-cast AZ61 alloy......
Semisolid joining of aluminum A356 alloy by partial remelting and mechanical stirring S. M. J. ALVANI1, H. AASHURI1, A. KOKABI1, R. BEYGI1 Materials Science and Engineering Department, Sharif... very much. Various semi-solid processes have been demonstrated to achieve the globular microstructure. In a partial- remelting condition, dendrites tend to transform into a rosettes and/or spherical......
of the infiltration casting process, with the infiltration advance, the remelting phenomenon would occur in the partial solidification region for the continuous heat transfer from the inlet region to the infiltration... between the remelting front and the infiltration front. It can be indicated from Fig.2 that the partial solidification would take place on the fibrous prefrom surface at the infiltration front, when......

The microstructure evolution of magnesium alloy AZ91D prepared by LVECP during partial remelting, and the effects of heating temperature and holding time on the partial remelted......
metallography on quenched microstructures, cooling curve thermal analysis, and thermodynamic calculations were further compared. Key words: semisolid; Mg-Gd-Y alloy; partial remelting; microstructural... and selected grain boundaries while other regions are still fully solid (Fig.3(a)). Moreover, the grain boundaries become illegible. Further remelting occurs at 590 °C (Fig.3(b)). Liquid has appeared......
