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.

本文以SLT为支撑体，利用Sn对传统的Ni基催化剂进行表面合金化处理，成功制备了Ni/Sn表面合金重整催化剂，将该催化剂用于甲烷和丙烷的CO_2重整和水蒸汽重整反应，研究结果表明，在Sn浓度很低的情况下，例如1wt%Sn含量，从能量角度看更易于形成表面合金，XPS数据也显示Sn更易于富集在Ni/Sn合金催化剂表面。

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.

While the invention as herein described is particularly directed to the treatment of zinc and zinc alloy surfaces, it has been observed that beneficial results are also obtained in the treatment of aluminum, aluminum alloy, magnesium and magnesium alloy surfaces to form a passivate film or coating thereon.

而由于此处所说的发明是特别向锌及锌合金表面处理、据观察，也取得良好效益待遇铝、铝合金、镁及镁合金表面形成钝化膜或涂层杂物。

It is shown that Mn and Ti had refined the microstructure,and formed to precipitation affluent of Mn or Ti ,which approved the performance of the Shape Memory Alloy.For a certain strain,the shape memory effect vayied functionly together with the aging time:alloy performance the best coorperative status that the martensite lathing was close and ordered,the precipitation rich of Mn and Ti dispersed orderly in the microstructure and little or even no eutectoid phase had precipited in the alloy ,in a special aging temperature and time. With the prolonger of the aging time,the different aging time affects the microstructure rulely.

结果表明：Cu-Al-X系形状记忆合金中，Mn和Ti的加入细化了组织，并且形成了富Mn和富Ti相，起到沉淀强化和弥散强化的作用；对于同一种变形量，合金在母相时效时，形状记忆效应随时效保温时间呈现规律性变化，不同时效温度下，合金对应一个不同的时效时间，此时合金的显微组织呈现最佳自协作状态，马氏体板条细密有序，富Ti和Al相均匀的弥散在组织中，合金中没有或很少有共析相出现，且随着时效时间的延长，在不同的特定温度下，Cu-24Al-3Mn-2Ti合金的组织会有规律性的变化。
