        摘要：By means of optical microscope, X ray diffraction, EMPA and TEM, the morphology, type, composition and forming condition of precipitates in Ni Mo type cast nickel base alloy are studied, and the influence of the precipitates on the uniform corrosion, intergranular corrosion and electrochemical corrosion properties are also studied. The results show that, in the range of 800￣1 100 ℃, Ni Mo type cast alloy can precipitate more or less Ni Mo intermetallic phases and M 6C. The alloy possesses a good property of uniform corrosion resistance in concentrate hydrochloric acid medium at temperature of 50 ℃ after the alloy has a solution heat treatment in 1 150￣1 180 ℃. And it has better intergranular corrosion resistance and electrochemical corrosion behaviour.

        摘要：By means of analytical transmission electronic microscope, this paper studied the interfacial microstructure of liquid stirred cast Al 2O 3（p）/Al Mg composites. The results showed that interface reaction products had a connection with the magnesium content of matrix. There was an orientation relationship between reaction product and Al 2O 3（p） particulate reinforcement, and there existed a large number of dislocations in the matrix near the interface.

        摘要：The solidifying structures and fracture appearance of alumina/aluminum silicon alloy composites manufactured by squeeze casting are studied. The results of study indicate that the distribution of alumina fibers is uniform; the fibers can serve as the site for heterogeneous nucleation of silicon phase; and the interface between the fibers and aluminum alloy matrix has great effect on mechanical properties of the composites. Improving manufacturing techniques should be started with controlling interface reaction and fining the structure of the composites.

        摘要：Gas hole characteristics of oxygen free copper rod with Up casting was observed by means of optical microscope（OM）. It is demonstrated that gas holes equally distribute in the district of circularity around the axial center of copper rod. According to solidification characteristic of Up casting and thermodynamic theory, the forming mechanism of gas holes was analyzed. It is presented that the gas holes were caused by vapours. Hydrogen reacts with oxygen and forms water vapour H 2O （g） , that is, 2+=H 2O （g） . Water vapours are associated with humid climate and wet raw materials.

        摘要：In the past ten years, the H 13 steel as hot working die materials has found spread application, especially it is of economic benefit for making complicated middle and large cast hot work dies. It is necessary to realize fully the cast properties of this steel, but few research works have been reported. In order to determine the factors influencing the casting properties of H 13 steel, a series of tests had been made out, the valuable data were obtained to lay the foundation for manufacturing cast hot work dies with high quality.
