Abstract
The aging precipitation behavior of super austenitic stainless steels 904L (4.32% Mo), 254SMo (6.06% Mo), and AL-6XN (6.29% Mo) with different Mo contents at 800°C-900°C was investigated by scanning electron microscopy, X-ray diffraction, and transmission electron microscopy, and the effect of Mo content on the σ-phase precipitation behavior of commonly used super austenitic stainless steels was explored. The effect of Mo content on the σ-phase precipitation behavior of commonly used super austenitic stainless steel was investigated. The results show that the super austenitic stainless steels with different Mo contents formed different numbers and shapes of σ-phases in the isothermal aging process, and the number of σ-phases of 254SMo and AL-6XN is much larger than that of 904L, and the shape of the σ-phases mainly shows coarse acicularity and elongation, while the σ-phases of 904L show fine granularity.
期刊介绍：
Materials Research is constantly evolving and correlations between process, structure, properties and performance which are application specific require expert understanding at the macro-, micro- and nano-scale. The ability to intelligently manipulate material properties and tailor them for desired applications is of constant interest and challenge within universities, national labs and industry.
