:A Influence of swirl number on melting process of aluminum melting furnace WANG Ji-min1, 2, YAN Hong-jie1, 2, ZHOU Jie-min1, 2, LI Shi-xuan3, GUI Guang-chen3 (1. School of Energy Science... Technology Co. Ltd., Suzhou 215008, China) Abstract: Based on validating results by heat balance test for aluminum melting furnace, a reasonable mathematical model which considering the feature......
with average diameter of 13.1 nm were synthesized by modified polyol process, and their melting point was observed to be about 40 °C less than that of bulk Sn. Even though Sn nanoparticles are solid and covered with thin PVP capping and oxide layer, Sn nanoparticles in solution agglomerate upon centrifugation, resulting in a melting point increase. Owing to stickiness of the PVP capping layer......

alloy (Ti-6Al-2.7Sn-4Zr-0.4Mo-0.45Si-0.1Y, mass fraction, %) has been additively manufactured using selective electron beam melting (SEBM). The resulting microstructure and textures were studied using... melting......
Trans. Nonferrous Met. Soc. China 22(2012) s813-s819 Process analysis of direct laser melting to fabricate layered hybrid beads Jeong-hwan JANG1, Sung-min MUN1, Tae-hyun KIM1, Young-hoon MOON1 School...: The successful fabrication of layered hybrid beads by DLM process is limited by dissimilar melting ranges of different powders. For the application of DLM process into manufacturing industries, target......

that on the same specimen, a convex surface with bigger radius of curvature is more likely to be molten and the melting loss speed is also faster than a flat and smooth surface. The thickness of compact layer on a smooth surface is much bigger than that of the convex surface. Therefore, the author supposes the compact layer is favorable in stabilizing the die surface material from further melting loss......
