    摘要:

    研究了一種包含有多尺度微結(jié)構(gòu)的高M(jìn)nN低Ni超級雙相不銹鋼25Cr-2Ni-3Mo-10Mn-0.5N經(jīng)過冷軋和退火后，多尺度晶粒度對點(diǎn)腐蝕和力學(xué)性能的影響。結(jié)果表明：多尺度微結(jié)構(gòu)與退火時(shí)間密切相關(guān)，在1050 oC，奧氏體與鐵素體平均晶粒大小隨著時(shí)效時(shí)間的增加而增加，時(shí)效1 min后，奧氏體和鐵素體的晶粒大小分別為1.5和7.18 μm。隨著多尺度晶粒的長大，樣品的抗拉強(qiáng)度，屈服強(qiáng)度和斷面收縮率下降，而樣品的耐腐蝕性能增強(qiáng)。多尺度微結(jié)構(gòu)對該雙相鋼25Cr-2Ni-3Mo-10Mn-0.5N的點(diǎn)腐蝕性能和力學(xué)性能起著重要作用

    Abstract:

    A high-Mn-N low-Ni superduplex stainless steel 25Cr-2Ni-3Mo-10Mn-0.5N with multi-scale microstructures has been prepared through severe cold rolling and annealing, and the effects of multi-scale grains on the pitting corrosion and mechanical properties have been investigated. The results show that the multi-scale microstructures have a strong relation with the annealing time, that is, the average grain sizes of austenite and ferrite increase with prolonging of the annealing time at 1050 oC, they have the minimum values of 1.5 and 7.18 μm, respectively, when the alloy is annealed for 1 min. The tensile strength, yield strength and reduction in area of the sample decrease with the growth of multi-scale grains, whereas the pitting corrosion resistance of the specimen is enhanced. The multi-scale microstructures play an important role on the pitting corrosion and the mechanical properties of superduplex stainless steel 25Cr-2Ni-3Mo-10Mn-0.5N.
