  1. Numerical Investigation of Burden Distribution in a Blast Furnace

    Sida Liu, Zongyan Zhou, Kejun Dong, Aibing Yu, David Pinson and John Tsalapatis

    Article first published online: 20 APR 2015 | DOI: 10.1002/srin.201400360

    Blast furnace burden distribution phenomena are captured by DEM approach, including justification of surface properties of spheres, burden trajectories from the chute tip, and formation of burden layers in the throat region. Proper values for rolling and sliding friction are recommended. Sensitivity tests are conducted to reveal the significance of particle surface properties on burden layer formation.

  2. The Study of Magnetic Force in Electromagnetic Forming of Small Size Sheet

    Xiaowei Chen, Wenping Wang, Min Wan and Anlin Long

    Article first published online: 20 APR 2015 | DOI: 10.1002/srin.201500097

    Magnetic force is calculated in electromagnetic forming of small size sheet by ANSYS/EMAG; small size sheet means that sheet length or sheet width, or both, is/are shorter than plane dimensions of coil. Induced current crowding effect is studied, and the influence of charging voltage, capacitance, separation distance, and relative position between coil and sheet on magnetic force are analyzed.

  3. Application of Computational Thermodynamics to Predict Growth of Intermetallic Phases in Superduplex Stainless Steels

    Article first published online: 20 APR 2015 | DOI: 10.1002/srin.201400277

    Computational thermodynamics are used to successfully predict precipitation and growth of intermetallic phases in superduplex stainless steels. The calculations accurately predict the classic C-shaped TTT Time-Temperature-Transformation curves, with most rapid growth at the “nose”. Verification of the calculations is done by comparing with a previous publication on precipitation of intermetallic phases in molybdenum and tungsten alloyed superduplex stainless steel weld metals.

  4. Enhancement in the Modeling of Temperature and Strain Rate-Dependent Plastic Hardening Behavior of a Sheet Metal

    Dohyun Leem, Hyuk-Jong Bong, Frederic Barlat, Myoung-Gyu Lee, Jung-Han Song and Daeyong Kim

    Article first published online: 17 APR 2015 | DOI: 10.1002/srin.201500006

    In this study, viscoplastic hardening behavior of aluminum alloy 3003 sheet is measured and modeled. Three different hardening models are utilized to fit experimental stress–strain data. Evaluation on each model for flow stress prediction convinces that the modified Hollomon/Voce law with additional inline image function improves prediction accuracy.

  5. Dynamic Magneto-Optical Imaging of Domains in Grain-Oriented Electrical Steel

    Hendryk Richert, Heidemarie Schmidt, Sandra Lindner, Morris Lindner, Benjamin Wenzel, Rocco Holzhey and Rudolf Schäfer

    Article first published online: 16 APR 2015 | DOI: 10.1002/srin.201500013

    The article presents the use of sensitive magneto-optical indicator film (MOIF) imaging as a comprehensive method for characterizing magnetic domains in grain-oriented electrical steels (GOES). MOIF imaging provides magnetic flux density distribution with a lateral resolution of 25 μm. Most important findings are (i) temporal resolution of 1 ms and (ii) the ability to be used on top of standard isolation layers.
