        摘要：Gradient function material of Al Fe alloy has been obtained by centrifugal casting. The amount of primary intermetallic compounds were distributed along centrifugal radius. The needle or plate like primary phase was turned into granlar and chinese script structure in appropriate Si, Mn and RE additions so as to improve mechanical property of Al Fe alloy.

        摘要：Low temperature aging for die casting Al alloy under appropriate technological condition can increase average strength and Brinell hardness more than 10% and 30% respectively. By means of this treatment it is possible to aviod deformation and bulge casting defects in solid solution treatment at high temperature as well as to increase mechanical properties for die casting. Microstructure observations during the period of aging treatment by SEM have been examined.

        摘要：The Ohno Continuous Casting technique has been successfully applied to the cast in process of optical fibres to a Al Mg alloy wire. Several kinds of coating materials were studied on their protective effects on the fibres. It was concluded that sugar bonded graphite coating gave the most effective results owing to its thinner, porous tructure and excellent high temperature collapsibility. The causes of fibre break were also discussed.

        摘要：Adding certain secondary precipitated phase forming alloying elements in Cu casting alloy, such as Cr, in comparsion with solid solution forming alloying elements for the crystalizer can remarkably improve its creep resistance at high temperature. Through creep test and electrical conductivity measurement, it is found that Cu casting alloy with 0.4%￣0.9% Cr is one of excellent metallic materials suited for the crystallizer.

        摘要：The Casting technique of fabricating SiCp/ZA27 by mechanical stirring of semi solid slurry and the effects of SiCp content and size on tensile and hardness of the composites have been discussed. The fracture surfaces of the composites have been examined by SEM. The results indicate that SiCp/ZA27 with uniform distribution of SiCp can be obtained. The tensile strength decreases with the increasing of SiCp content and size. The apprearance of fracture is characterized by partial dimples, and formation mechanism is different with variance in SiCp content and size. The hardness of composites increases with the increasing of SiCp content V （SiCp）<5%, while it decreases at SiCp content V （SiCp）>5%. The hardness of composites reinfored by finer SiCp is higher than that of composites reinfored by coarser.

        摘要：The effect CFF with different hole on structure and properties of ZL204A has been studied in this paper. The research indicates that filtrating ability is raised and grain is refined by increasing hole density of CFF, while tensile strength and yield strength of ZL204A are decreased because of severe porosity, but its elongation is increased after a reduction.
