Atomic simulations for surface-initiated melting of Nb(111) YANG Xi-yuan(阳喜元), WU Dan(吴 丹) College of Physics and Electronics, Hunan University of Arts and Science, Changde...; Abstract: A modified analytic embedded-atom model(MAEAM) was applied to investigate surface premelting and melting behaviors of Nb(111) plane by molecular dynamics(MD) simulations. First......
" name="ChDivSummary">With the Voter-Chen version of embedded-atom model (EAM) potential and molecular dynamics, the melting of Ni3Al alloy was simulated by one-phase (conventional) and two-phase approaches. It is shown that the simulated melting point is dependent on the potential and the simulation method. The structures of the melts obtained by different simulation methods were analyzed......

: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......
