Abstract

Using the THERMOCALC software package, phase state calculations in the temperature range of 500–1600°C have been performed for eleven compositions of chromium-manganese stainless steels with a manganese concentration ranging from 0 to 20% and with the limiting equilibrium nitrogen concentration corresponding to each composition. The results have been used for plotting a phase diagram making it possible to evaluate the effect of manganese exerted on the extent with respect to the temperature and manganese concentration of the domains of existence of austenite, ferrite, chromium nitride, carbides and σ phase affecting the processing and operational properties of nitrogen-alloyed corrosion-resistant steels.

变锰浓度Cr-Mn-N钢相图的计算构建

摘要

使用 THERMOCALC 软件包，已经对 11 种铬锰不锈钢成分在 500-1600°C 的温度范围内进行了相态计算，其中锰浓度范围为 0-20%，极限平衡氮浓度对应于每个组成。结果已用于绘制相图，从而可以评估锰对奥氏体、铁素体、氮化铬、碳化物和 σ 相的存在域的温度和锰浓度的影响程度。氮合金耐腐蚀钢的加工和操作性能。
