brazing for the aluminum clustered tube of refrigerator was analyzed. According to characteristic of aluminum and aluminum alloy, a kind of high frequency power supply was devised and applied, and the technology parameters applied in the practical production were pronounced. The results show that aluminum and aluminum alloy can be heated quickly by high frequency induction. In the proper frequency......
and one powder were employed: 99.9% high purity binary eutectic Al-Si alloy, the high purity metal Ca and the powder of TiH2 (with granularity of 47 μm). Closed-cell aluminum foams are produced by molten...] both made great progress in the production technology of metal foam materials. Compared with the traditional materials, aluminum foam materials have the advantages of low density, high stiffness......

temperature and an appropriate molar ratio of resin-derived carbon to silicon are favorable for producing high purity silicon carbide powders. It is found that the silicon carbide content increases slightly...,the formation of silicon carbide is based on the liquid-solid reaction,and high purity (99.8wt%) silicon carbide powders can easily be obtained. It can also be found that the optimum molar ratio of resin......
