中文摘要：

有不同 N 内容的三高氮的不锈钢被为一张通行证的相等隧道的尖压成功地处理，并且他们的微观结构和机械性质被调查。营舍的微观结构越过营舍厚度是异构的，这被发现，导致在由于不同变丑条件的机械性质的差别。相对低的力量，高一致的延伸，和为在营舍的底部的样品的高变硬工作的率与在顶处理的那些比较被完成。同时，变丑双胞胎的密度与 N 的内容增加了，这被观察；因此，合金的力量和延伸与 N 的内容增加，导致好 strengthductility 联合。

英文摘要：

Three high-nitrogen stainless steels with different N contents were successfully processed by equal-channel angular pressing for one pass, and their microstructures and mechanical properties were investigated. It was found that the microstructure of the billet was heterogeneous across the billet thickness, resulting in the difference in the mechanical properties due to the different deformation conditions. A relatively low strength, high uniform elongation, and high work- hardening rate for the samples at the bottom of the billet was achieved in comparison with those processed at the top. Meanwhile, it was observed that the density of deformation twins increased with the content of N; accordingly, the strength and elongation of the alloys increase with the content of N, resulting in a good strength-ductility combination.
