| 2 | Diffusion mechanism of dezincification in double phase brass exposed to seawater显示文摘Zinc diffusion kinetics of double phase brass as they were corroded in seawater was investigated by means of metallography microscope and mathematics regression analysis. The results showed that, the dezincification corrosion of β phase continuous HMn58 2 brass is characterized by β phase volume diffusion, while that of α phase continuous HSn62 1 brass is controlled by α phase grain boundary diffusion. Apparent diffusion coefficients of zinc in both types alloys were calculated out by founding diffusion equation and boundary conditions. It was found that the value of theoretical calculation is close to that of experimentally measured, and it confirmed that Sn element inhibits dezincification of brass. The relativity between the dezincification depth and corrosion rate of different double phase brasses immersed in seawater was revealed. : Zinc diffusion kinetics of double phase brass as they were corroded in seawater was investigated by means of metallography microscope and mathematics regression analysis.

| 4 | Intergranular precipitation of copper-nickel alloys induced by seawater corrosion显示文摘This paper presents the observed grain boundary structure of Cu:Ni 70:30 alloy tubes before and after exposure to seawater. The results show that the thin platelet precipitates along grain boundaries of the alloys nucleated in the process of heat treatment and coarsened when they were exposed to seawater, indicating that the coarsening was induced by seawater corrosion. The diffraction image of the precipitate is fringe structure and possessed its own wave lengths. The fine scale structure is susceptible to intergranular corrosion, which could be confirmed by corrosion morphology observation of specimens after a long-time seawater exposure. The experiments were carried out by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), optical metallography (OM) and tensile testing etc., detecting corrosion morphology, microstructure and the mechanical property change due to the precipitation coarsening induced at grain boundaries of the specimens during exposure in seawater. | LIN LeYun ZHAO YueHong | 2009 | Chinese Science Bulletin2009，54，19： | 1 |
| 5 | THE INFLUENCE OF RESIDUAL STRESS ON THE CORROSION RESISTANCE OF H68A BRASS TUBES IN SEA WATER显示文摘This paper reveals the morphological characteristics of the cracks formed in H68A brass tubes fully immersed in seawater, and studies the depth profiles of the residual stress of the tubes. Tbe great residual stress in the wall results in stress-corrosion cracking, and the unique morphology of the cracks is due to the uneven distribution of residual stress through the depth of the tube. | Yan, Yumin Zhu, Xiaolong Lin, Leyun Beijing General Research Institute for Nonferrous Metals, Beijing 100088, China | 1993 | 中国有色金属学会会刊:英文版1993，3，1： | 1 |
