经轧制的

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 split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
