TEM characterization of precipitates in the segregated regions of a low-carbon, low-manganese, titanium-added steel

Journal Article


Abstract


  • A concentric solidification technique has been employed

    to simulate sulphide precipitation at the centreline of a

    continuously cast low-carbon, low-manganese, titaniumadded

    steel slab. Selected precipitates were identified

    using transmission electron microscopy following sample

    preparation by focused ion beam milling techniques. FeTiS2

    and hexagonal MnS containing iron atoms form in close

    proximity to each other in super-saturated areas of the

    concentrically solidified sample. The presence of FeTiS2

    precipitates in low-carbon steel has been verified for the

    first time, and the crystal structure determined by electron

    diffraction analysis as a trigonal CdI2-type with a P3m1 space

    group and lattice parameters of a = 0.341 nm and c = 0.569

    nm.
