        摘要：The results of hydrogen determination in aluminium melt by british apparatus HYSCAN Ⅱ show that both hydrogen porosities and hydrogen content in raw materials possess the character of heredity. The hydrogen heredity in porosities is a part of the hydrogen heredity in raw materials. Accordingly, a concept of heredity efficiency has been proposed.

        摘要：The curved ceramic lined pipes have been produced by gravitational separation SHS method in combination with rotating technology. Based on SiO 2 addition the influences of NaF additive on synthesis process, structure and properties of curved pipes have been investigated. It is obtained that NaF in the form of Na 3AlF 6 cryolite structure and Na 2SiO 3 monocline structure exist at the boundary of ceramic dendrite with tight fineness because of constituent undercooling. Acting as a diluent during thermite combustion process, NaF will reduce the combustion temperature and propagation rate; During ceramic solidification NaF promotes ceramic densification through reducing crystallization temperature and dynamic viscosity of the melts.

        摘要：The sliding wear behavior of 3 dimensional continuous aluminum alloy matrix network porous ceramics composites has been investigated under dry sliding condition. The results showed that the wear resistance of the composites was superior to that of matrix and the wear rate of the composite against grinding ring is more than that of matrix, but the total wear rate of composite GCr15 system is less than that of matrix GCr15 system.

        摘要：The electrolytic Al Si Ti alloy possesses very strong modifying effect of silicon, iron and titanium and excellent ability to refine the α Al dendrite. The refined microstructure is insensitive to cooling rate, being independent of casting thickness. The Al Si alloys with some percentages of electrolytic Al Si Ti alloy charge exhibit high ultimate tensile strength at room and high temperature, excellent toughness and ductility, compared with conventional Al Si alloys. The car parts made of electrolytic Al Si Ti alloy result in good performance.

        摘要：FM（EPC） has been developed for 33 years in China. In practice, however, a rapid development was obtained just after the Foundry Association Full Mold Casting Committee was founded at the end of this 80’s （at that time only 18 members registered in the Committee）, espccially in the recent years. As shown in an incomplete statistic, at present there are about 110 groups working on the research and application of this kind of new technology, which is about 6 times the figure when the Committee was founded, Among them are 14 high academies or research institutes and 15 companies or plants for raw materials, auxiliary materials, and exclusive facilities. In 1997, the output of EPC castings runs up to 25 800 t in China, as is 2 times as much as in 1995（98% of the output is of ferrous castings） Considering that it is only 16% of the curent throughput, this kind of new lechnology is very promising in China.

The main products of the companies involve investment castings, aluminum castings, wax, ceramic cores, Al alloy ingot, investment casting alloys, injecting wax machine etc. The suggest was given the specialized and superior factories in which all kinds of allys, ceramic cores, waxes, dies should be set up with the whole trade support in investment casting industry. So that the outer condition of our investment casting factories could be improved and their competitive ability in the world could be enhanced quickly.
