  • high performance Steel Research front historical account of Research activities
    Journal of Bridge Engineering, 2004
    Co-Authors: Atorod Azizinamini, Karl E Barth, Robert J Dexter, Camille Rubeiz
    Abstract:

    This paper provides a summary of the major Research studies conducted or being conducted in the U.S., to address design issues related to use of high performance Steel (HPS) in bridge construction. Emphasis of the paper is on the work related to HPS-485W Steel, which has specified minimum yield strength of 485 MPa (70 ksi). Design issues that are addressed in this paper include (1) flexural capacity of compact and noncompact HPS sections in negative bending; (2) issues related to ductility of HPS composite girders in the positive sections (this section presents a simplified ductility check for composite plate girders); (3) tensile ductility of HPS plates; (4) shear capacity of the hybrid Steel plate girders; (5) live load deflections; and (6) brief overview of the work that is underway to develop innovative bridge configurations capable of incorporating the advantages of HPS.

  • Effect of Ultra-Fast Cooling on Microstructure of Large Section Bars of Bearing Steel
    Journal of Iron and Steel Research International, 2009
    Co-Authors: Yan K. Sun, Di Wu
    Abstract:

    The ultra-fast cooling technology of large section bars and the microstructure for different cooling patterns were studied by optical microscope, transmission electron microscope and energy spectrometer. The results indicated that the large section bars were passed through the zone of secondary carbide precipitation quickly by ultra-fast cooling technology (UFC) at instantaneous cooling rate of about 200°C/s and the finishing cooling temperature was higher than Ms. The lamellar spacing of pearlite decreased and the microhardness increased with decreasing the rereddening temperature. The precipitation of network carbide was restrained when re-reddening temperature was 690°C. And fine laminated pearlite was obtained through transformation of pseudopearlition that induced the reduction of the diameter of pearlite grain and refinement of the lamellar spacing of pearlite, so ideal microstructures of promoting spheroidizing annealing were obtained. © 2009 Central Iron and Steel Research Institute.
