        摘要：A kind of composite modification agent for hypereutectic Al Si alloy refinement has been developed. It has a good effect on refining both primary crystal Si and eutectic Si.Both the biggest size of massive primary silicon phase and length of bar eutectic silicon phase are below 100 μm in hypereutectic Al Si alloy after being modified. As a result,the mechanical properties of refined alloy exceed those of all other hypereutectic Al Si alloy with the same composition in domestic and foreign countries.

        摘要：A new Al 5Ti 0.3C master alloy refining agent is prepared in lab, which has a good refinement effect with 0.1%～ 0.2% addition on pure aluminum. Higher addition levels w （Ti）=0.15% are needed to achieve good refining effect for Al Si alloy while refinement fading occurs early. Mg can enhance the refining ability of the master alloy.

        摘要：Influence of Al 5Ti,Al 5Ti B on the grain refinement and the tensile properties of ZL108 alloy with T6 state is studied. The results showed that high Si in Al Si alloy restrict the effects of Al 5Ti on the grain refinement of ZL108 alloy.0.20%～0.25% Ti content could improved properties of ZL108 alloy. The influence of Al 5Ti B on the properties of ZL108 alloy is better than those of Al 5Ti. Tensile strength and elongation is improved and α grain is refined for ZL108 alloy with 0.30%～0.35% Ti content and 0.06%～0.07% B content.

        摘要：The ceramic lined nodular cast iron was fabricated by the SHS centrifugal thermit process. The influence of combustion synthetic process on microstructure and properties of nodular cast ison was investigated. The results showed that the composite pipe is composed of ceramic layer, pearlite transition layer and cast iron layer with white iron layer, heat diffusion zone and matrix of base nodular cast iron. The resistance to wear and corrosion of nodular cast iron pipe was increased remarkably by SHS. Combustion synthetic process almost has no effect on outer layer structure of nodular cast iron with the good properties of toughness and erosion resistance of nodular cast iron to be reserved.

        摘要：Influence of calcium stearate on the hot properties of precoated sand has been studied. The results showed that hot toughness, softening point, sink rate,hot bending strength and resistance to hot tear of precoated sand are improved with an addition of calcium stearate more than 0.3% while the excessive addition of calcium stearate is subversive for stability at high temperature. The relationship between calcium stearate and sand core as well as casting quality of cylinder head of diesel engine for example is analyzed.

        摘要：The research showed that basin is the more important feeding resource than runner in runner type gating system in lost wax casting. Therefore, on the basis of the basin as feeding resource, runner and ingate as feeding channel, a new design method for runner type pouring and feeding system in investment casting was developed. The corresponding feeding mathematical pattern and allowable total weight listed for casting cluster with different basin were established after analyzing the practical feeding of basin and the calculating process for design was described in detail.
