    In this study, the microstructure and properties of the surface and interior part of ultra-heavy steel plate (>200 mm) under three potential heat treatment technologies are examined. The relationship of processing-structure-property is carefully studied, which provides valuable guidance for the optimization of the comprehensive mechanical properties across thickness of ultra-heavy steel plate.

  2. Effect of Interphase Hardness and Elastic Modulus on Fracture Behavior during Hole Expansion Testing of Hot-Rolled Steels with Low-Temperature Transformation Microstructures

    This study investigates the fracture behavior during hole expansion testing of a 980 MPa hot-rolled steel consisting of a tempered martensite matrix and granular bainite, with particular focus on analyzing the microvoid initiation and crack propagation during plastic deformation. Specifically, the study focuses on the interphase hardness, elastic modulus, and corresponding fractography with dislocation density.

    The high-temperature united constitutive model of non-oriented electrical steel is established based on the transformation kinetics equation and dislocation density theory, which specially considers the effect of phase transformation on the deformation resistance. The effects of temperature and phase structure on the yield stress, material constant, hardening coefficient, and softening coefficient in different phase regions are quantified and compared.

  4. Filter Functionalization with Carbon Nanotubes and Alumina Nanosheets for Advanced Steel Filtration

    Enrico Storti, Steffen Dudczig, Anne Schmidt, Gert Schmidt and Christos G. Aneziris

    Carbon-bonded alumina filters coated with MWCNTs and alumina nanosheets are tested in contact with molten steel at 1650 °C. After 60 s, fine endogenous inclusions are found on the top layers. Investigations of the steel samples after the test reveal excellent filtration efficiency for 10 s contact time. However, these filters also generate new silicate inclusions with increasing time. Apparently, the coating composition affects the type of inclusions, which are produced.

  5. Formation of Spinel Phases in Oxidized BOF Slag under Different Cooling Conditions

    A BOF slag sample from Ning Steel group in China is treated by oxidizing at 1500 °C for 30 min and subsequently cooled by either water or air, as well as in the furnace. The treated samples are characterized together with some related equilibrium calculations with suggestions proposed to enhance the slag recycling.
