Variations for pure Cu melt viscosity with different atmospheres

Geng Haoran; Xue Xianying; Yu Ke; Liu Jian-tong

The viscosity of Cu melt is obtained to be in the ranges from 2.418 to 3.039 mPas under vacuum atmosphere (2 Pa), from 2.907 to 3.425 mPas under nitrogen gas atmosphere and from 3.352 to 4.015 mPas under argon gas atmosphere. The activation energy is estimated to be 0.224, 0.162 and 0.150 eV for the vacuum atmosphere (2 Pa), nitrogen gas atmosphere and argon gas atmosphere, respectively. The results reflect the essential structural change in the Cu melt by using different atmospheres.

Temperature dependence of densities of Sb and Bi melts

Geng Haoran; Sun Chun-Jing; Wang Rui; Qi Xiaogang; Zhang Ning

The densities of Sb and Bi melts were investigated by an improved Archimedean method. The results show that the density of the Sb melt decreases linearly with increasing temperature, but the density of the Bi melt firstly increases and then decreases as the temperature increases. There is a maximum density value of 10.002 g/cm3 at 310°C, about 39°C above the melting point. The temperature dependence of the Sb melt is well fitted with the expression ρ=6.8590−5.8105×10−4T, and that of the Bi melt is fitted with ρ=10.3312−1.18×10−3T. The results were discussed from a microstructure viewpoint.

The abrasive wear properties of Al-Mg-Si3N4 metal matrix composites

Wang Shou-ren; Sun Bin; Geng Haoran; Wang Yingzi

One kind of three-dimensional network structure, reinforced aluminum magnesium matrix composites, has been prepared by pressure-assisted and vacuum-driven infiltration technology. The composites interpenetrated with ceramic have higher wear resistance than the metal matrix owing to their special topology structure. The reinforcement volume fraction has a large effect on abrasive wear. The wear rate decreases with the increase of the volume fraction of reinforcement and increases with the increase of sliding time and applied load. The wear mechanism of the composites (abrasive wear) differs greatly from the matrix alloy (adhesive wear).
