    The initial secondary austenite phase (γ′) transformation occurs only in the cooling process and under hot tensile test condition. The γ′ precipitates in the temperature range of 950–1150 °C. The γ′/δ phase interface is coherent at 950 °C. However, the γ′/δ phase interface is not coherent at 1100 °C.

  2. Study of Inclusions in High Sulfur, Al-Killed Ca-Treated Steel via Experiments and Thermodynamic Calculations

    In the production of special steels, inclusions have a significant influence on final product quality. The main objective of this study is to conduct a thermodynamic study aimed at preventing clogging problems during continuous casting (CC) and the formation of undesirable inclusions. Alumina (Al2O3), spinels, and calcium sulfide (CaS) are potential sources of defects during rolling and steel forging.

  3. Formability of AHSS under an Attach–Detach Forming Mode

    The FE simulation results demonstrate that the thinning tendency is limited by the simultaneous effects of friction coefficient reduction and springback after each detachment. It explains the increased drawability when the non-conventional forming mode is used compared to the conventional V-mode, as shown by the cup-drawing test results.

  4. Influence of B2O3 and TiO2 on Viscosity of Titanium-Bearing Blast Furnace Slag

    Yanhong Gao, Lingtao Bian and Zhongyu Liang

    Article first published online: 15 JUL 2014 | DOI: 10.1002/srin.201400039

    All the viscosities are within 0.2 Pa s for high temperature (over 1633 K in this experiment), which is less than that of the B-free slag. However, the value increases sharply when temperature is below break point temperature. In addition, an increase in the value of B2O3 content reduces significantly break point temperature and descent rate of temperature rises with increasing B2O3 content.

  5. Effects of MnO and CaO/SiO2 Mass Ratio on Phase Formations of CaO[BOND]Al2O3[BOND]MgO[BOND]SiO2[BOND]CrOx Slag at 1673 K and PO2=10−10 atm

    Article first published online: 15 JUL 2014 | DOI: 10.1002/srin.201400117

    Manganese is found to be enriched in spinel and liquid. The spinel increases in size with increasing of MnO and decreasing of CaO/SiO2 ratio. Disintegration is found in samples with increased MnO content and CaO/SiO2 ratio, which can be interpreted by increase of the size of Ca2SiO4 with increase of MnO content and CaO/SiO2 ratio.
