  • Effect of Cryogenic Treatment on AISI M2 High Speed Steel: Metallurgical and Mechanical Characterization
    Journal of Materials Engineering and Performance, 2012
    Co-Authors: Simranpreet Singh Gill, Jagdev Singh, Rupinder Singh, Harpreet Singh
    Abstract:

    This study aims to present the Metallurgical and mechanical characterization of cryogenically treated AISI M2 high speed steel (HSS) in terms of carbide precipitation and wear behavior. The samples of commercially available conventionally quenched and tempered AISI M2 HSS were procured and subjected to cryogenic treatment at two levels −110 °C (shallow treatment) and −196 °C (deep treatment) of temperature. The microstructures obtained after cryogenic treatments have been characterized with a prominence to comprehend the influence of cryogenic treatment vis-à-vis conventional quenching and tempering on the nature, size, and distribution of carbides. The mechanical properties such as hardness and wear rate of the specimens have also been compared by performing Rockwell C hardness test and pin-on-disc wear test, respectively. Microstructures, hardness, wear rate and analysis of worn surface reveal the underlying Metallurgical Mechanism responsible for the improving mechanical properties of the AISI M2 HSS.

  • Metallurgical Mechanism and niobium effects on improved mechanical properties in high carbon steels
    HSLA Steels 2015 Microalloying 2015 & Offshore Engineering Steels 2015: Conference Proceedings, 2015
    Co-Authors: Steven G Jansto
    Abstract:

    The technological development of value-added applications for niobium (Nb) microalloyed structural steels has expanded into the high carbon long products sector. Micro additions of 0.005 to 0.020%Nb in various high carbon steel compositions have exhibited improved processing, such as wire drawability or formability during manufacturing, higher productivity at reduced operational cost as well as improved mechanical properties compared to traditional non-Nb bearing high carbon steels. Although the Nb solubility is limited in high carbon steels compared to low carbon steels, the optimized Nb content has been defined based on experimental results and now transferred into industrial operations. The Nb delays the pearlite transformation, hence resulting in a finer interlammelar spacing compared to traditional high carbon pearlitic steels. Consequently, the optimized Nb content leads to improved mechanical properties due to this finer interlamellar pearlite spacing. Opportunities exist to transfer this new Nb-technology into wire rods, bolts, rails and tire cord.

  • MicroNiobium Alloy Approach in Medium and High Carbon Steel Bar, Plate and Sheet Products
    Metallurgical and Materials Transactions B, 2014
    Co-Authors: Steven G Jansto
    Abstract:

    The recently developed application of the MicroNiobium Alloy Approach^® in medium- and high-carbon steel long products, sheets, and plate steels enhances both the Metallurgical properties and processability, as well as reducing the operational cost per tonne of production. The process and product metallurgy improvements relate to the Nb-pinning effect of the austenite grain boundaries. The Metallurgical Mechanism of the MicroNiobium Alloy Approach is related to the retardation of austenite grain coarsening during reheat furnace soaking of the billets, slabs, or shapes before rolling. Variable grain size is induced by temperature fluctuations and inhomogeneity during the heating of the slabs in the reheat furnace. Such fluctuations can occur because of variations in the air- to gas-ratio, directly affecting the adiabatic flame temperature and heat input into the slabs. This approach contributes to the achievement of an ultrafine grain, homogeneous higher carbon microstructures that exhibit superior toughness, high strength, less mechanical property variation in the final hot-rolled product, and reduced cost of quality. The reduced cost of quality far exceeds the additional alloy cost for the Nb addition.
