- Effect of FeO/MgO Ratio on Dissolution and Leaching of Magnesiowüstite
Ida Strandkvist, Åke Sandström and Fredrik Engström
Version of Record online: 13 JAN 2017 | DOI: 10.1002/srin.201600322
The dissolution and chromium leaching of magnesiowüstite with different FeO/MgO ratios is investigated. The dissolution and chromium leaching correlates with the FeO/MgO ratio. As seen in the Figure, the Cr-leaching decreases as the FeO content increases.
- Evolution of Microstructure, Properties and Texture of a Two-Phase Low-Carbon Steel at Cold Asymmetric Rolling

Asymmetric cold rolling instead of conventional symmetric cold rolling of low-carbon steels promises significant reduction of rolling forces and grain refinement with simultaneous improvement of mechanical properties and drawability. Rolling forces at asymmetric cold rolling of steel 22MnB5 could be up to 50% lower than at conventional symmetric cold rolling with the same reduction per pass of 45%. This is attributed to the additional shear strain in material at asymmetric rolling, which lead to improvement of strength properties up to 9% in comparison with symmetric rolled material due to so-called texture strengthening.
- Precipitates and Precipitation Strengthening of Sanicro 25 Welded Joint Base Metal Crept at 973 K

Secondary NbCrN and Cu-rich particles, which precipitate Secondary NbCrN and Cu-rich particles, which precipitate in Sanicro 25 welded joint base metal after creep at 973 K, keep fine during creep. They are the key precipitates in improving the creep rupture strength of Sanicro 25 welded joint. At least 58% of precipitation strengthening is contributed by secondary NbCrN and 28% is contributed by Cu-rich particles.
- The Effect of Large Stress on Bainitic Transformation at Different Transformation Temperatures
Mingxing Zhou, Guang Xu, Haijiang Hu, Qing Yuan and Junyu Tian
Version of Record online: 29 DEC 2016 | DOI: 10.1002/srin.201600377
The effect of large stress above the yield strength of austenite on the microstructure and kinetics of bainitic transformation at different transformation temperatures is investigated. It is the combination of stress and small prior deformation that affects bainitic transformation with a large stress. The promotion of large stress on bainitic transformation is more significant at a lower temperature.
- Beneficiation of High-Phosphorus Siderite Ore by Acid Leaching and Alkaline Oxide Reinforced Carbothermic Reduction-Magnetic Separation Process
Chao Lv, Shuming Wen, Kun Yang and Shaojun Bai
Version of Record online: 29 DEC 2016 | DOI: 10.1002/srin.201600314
This paper provides a method for beneficiation of high-phosphorus siderite ore. A combined metallurgy process is developed, which includes dephosphorization using H2SO4 leaching at low concentration, reinforces carbothermic reduction with alkaline oxide additives (Na2CO3 and CaO) and magnetic separation process. An iron concentrate has a high metallic iron content and a low content of harmful impurities, which can be used as a raw material for iron-making.
