| 1 | Filling ability of semi-solid A356 aluminum alloy slurry in rheo-diecasting显示文摘The effects of slurry temperature,injection pressure,and piston velocity on the rheo-filling ability of semisolid A356 al- loys were studied by the reho-diecasting methods.The results show that the slurry temperature of the semi-solid A356 aluminum al- loy has an important effect on the filling ability;the higher the slurry temperature,the better is the filling ability,and the appropriate slurry temperature for rheo-filling is in the range of 585-595℃.The injection pressure also has a great effect on the filling ability, and it is appropriate to the rheo-filling when the injection pressure is in the range of 15-25 MPa.The piston velocity also has a great effect on the filling ability,and it is appropriate to the rheo-filling when the piston velocity is in the range of 0.072-0.12 m/s.The filling ability of the slurry prepared by low superheat pouring with weak electromagnetic stirring is very good and the microstructural distribution in the rheo-formed die castings is homogeneous,which is advantageous to the high quality die casting. | Yuelong Bai Weimin Mao Songfu Gao Guoxing Tang Jun Xu | 2008 | Journal of University of Science and Technology Beijing2008，15，1： | 5 |
| 2 | New method for the preparation of semi-solid AlSi7Mg alloy slurry显示文摘The effects of pouring temperature and short electromagnetic stirring with low strength on the microstructures of AlSi7Mg alloy were investigated. The results show that if liquid AlSi7Mg alloy is poured at 630 or 650°C, many primary α-Al grains in the solidified melt are rosette-like, and only a small number of them are spherical. However, if liquid AlSi7Mg alloy is poured at a lower superheat and meanwhile is stirred by an electromagnetic field at a low power for a short time, then most primary α-Al grains in the solidified melt become spherical, and only a few are rosette-like. The theoretical analysis indicates that the strengthened melt flow motion induced by the short electromagnetic stirring makes the temperature field more homogeneous in the melt, which is poured at a lower superheat, and makes the primary α-Al grains deposit in a larger region at the same time, so this new solidification kinetic condition leads to the microstructure of spherical primary α-Al grains. The experiments also demonstrate that pouring at an appropriate superheat and stirring by an electromagnetic field at a low power for a short time is a good new method for preparing the semi-solid slurry or billet of AlSi7Mg alloy. | Weimin Mao Hai Lin Yuelong Bai Songfu Gao | 2007 | Journal of University of Science and Technology Beijing2007，14，1： | 2 |
