Low-activation Mn–Cr austenitic stainless steel with further reduced content of long-lived radioactive elements

Effects of Mn addition on the magnetic property and corrosion resistance of bulk amorphous steels

“…In comparison, the magnetic permeabilities of nonmagnetic crystalline steels such as the 316 stainless steels and the Fe-Cr-Mn high manganese austenitic steels lie between 1.0028 and 1.064. The concrete compositions denoted by the symbols listed in Table 2 can be found in references [17,18]. It is demonstrated that the magnetic permeabilities of our designed BASs are much lower than those of the nonmagnetic crystalline steels.…”

Effect of tungsten and tantalum on the low cycle fatigue behavior of reduced activation ferritic/martensitic steels

“…However, the high contents of nickel, molybdenum and cobalt in these steels, especially in the austenitic stainless steels, cause problems of long life activation [2,3]. Therefore a lot of research devoted to adjustment of alloying elements is being carried out which has led to the development of several stainless steels [4,5] and chromium steels [6,7]. For example EUROFER97, is a modified composition of conventional ferritic/martensitic 8-12% CrMoVNb steels (modified 9Cr-1Mo steel) developed mainly by substituting elements such as molybdenum and niobium with tungsten and tantalum respectively which have the same metallurgical functions as alloying elements and achieve fast radioactive decay properties.…”

Thermodynamic Calculation Study on Effect of Manganese on Stability of Austenite in High Nitrogen Stainless Steels

“…[9] Then, Hull and Speidel diagrams took both low-manganese and high-manganese steels into consideration, but they are found still inaccurate for high-manganese stainless steels. [10][11][12] For high-manganese HNS, a new diagram with a different equivalent formula was proposed in our previous study. It is obvious that manganese plays an important role in the development of diagrams for stainless steels.…”

“…Many previous studies also concluded that the role of manganese was dualistic and dependent on its content in Fe-Cr-Mn-C, Fe-Cr-Mn-N, and Fe-Cr-Mn-Ni steels, [6][7][8]10,11,18] but they never considered the interactions among the alloying elements. Only a few researchers found that chromium weakened the austenite stabilizing ability of manganese in Fe-Cr-Mn-Ni and Fe-Cr-Mn-C steels.…”

“…Meanwhile, the applicable scopes of these diagrams depend on the manganese content in the studied steels, which coincides well with previous studies. [9][10][11][12][13][14][15] To sum up, the effect of manganese on the stability of austenite in HNS is very complex, and strong interactions exist between manganese and the other alloying elements. That is to say, the activity coefficients of given by Hull, [6] Schaeffler, [4] Delong, [5] and Wang et al [8] are also shown.…”
