  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    University essay from KTH/Materialvetenskap

    Author : Helena Ek Jendrny; [2023]
    Keywords : AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Abstract : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. READ MORE

  5. 4. The development of scanning X-ray diffraction phase mapping techniques using automated Rietveld refinements.

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Johannes Brask; [2018]
    Keywords : Retained austenite X-ray diffraction XRD Scanning X-ray diffraction SXRD; Physics and Astronomy;

    Abstract : A methodology for determining inhomogeneities in microstructural features has been established using scanning X-ray diffraction (SXRD) and automated Rietveld refinements. The method has proven successful for spatially resolved quantitative phase analysis or "phase mapping" of retained austenite on a variety of martensitic steel samples, including carbon case-hardened steel bars and quenching and partitioning (Q&P) steel sheets.
