This invention discloses a preparation method for anti-corrosion rare earth magnet material characterizing that it takes the optimized grain-boundary phase design as the starting point on the basis of a dual alloy method to select Nd base alloy with high crystal forming ability as the assist alloy and reduces the temperature of the press mold blank in a quartz container to room temperature from over grain-boundary phase melting point with the water extraction way to get enough cooling rate and guarantee the non-grain-boundary phase, compared with the material of the same composition prepared by ordinary method, the weightlessness of this invented material reduces over 30% after testing the weightlessness of the material by laying it for 96 hours under 121deg.C, 2 atmosphere and 100% humid environment to show the advanced performance of anti-corrosion.

The high temperature ductility of Monel K-500 alloy with minor element additives is much better than that of the standard Monel K-500 alloy (1〓 alloy).

添加微量元素的Monel K-500合金的高溫塑性均較標(biāo)準(zhǔn)的MonelK-500（1〓合金）有所提高。

Seven experimental Monel K-500 alloy were prepared with various addition schemes. The microstructures of seven experimental alloys in hot roll condition were examined, which showed no obviously difference. However, after solution treatment, the grains of the Mg added 2〓 alloy grew apparently, which are much bigger than the grain size of standard Monel K-500 alloy with no additive. It implies that the minor Mg element had purified the grain boundary.

The research results show for low Sn concentrations, for example 1wt%Sn with respect to Ni, the Ni/Sn surface alloy is energetically preferred. We have also used XPS to characterize the catalysts. The quantified Sn and Ni XP spectra for Ni/Sn/SLT catalysts show that Sn preferentially segregates to the surface of the Ni/Sn alloy. We demonstrate that supported Ni/Sn alloy catalyst provides significantly higher reforming reactivity and resistance to deactivation via carbon deposition than supported monometallic Ni catalyst both in steam reforming of CH4 and CO_2 dry reforming.

In order to reduce the lead dust which overswing out of the high temperature lead pot and meet the national minimum requirement, the liquid metal alloy was used as protective covering, different composition of Cu-Al alloy were studied. Its liquidity, oxidation resistance and leak tightness performances of these two types of Cu-Al alloy were studied.
