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合金的高温塑性均较标准的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.

7种合金在轧制状态时的显微组织并无明显的差别，但经固溶热处理后，加Mg的2〓合金的晶粒明显长大，大于未加微量元素的MonelK-500合金的晶粒，显示Mg在合金中有净化晶界的作用，但同时添加了Mg、Cr、Co元素的6〓合金，它们的共同作用使晶粒长大的阻力又增加了。

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.
