(TU Delft (OLD) MSE-5) Date 2018 Abstract In this paper, we describe the effects of mechanical loading on bcc-to-bcc phase transformations of an Advanced High Strength Steel during cooling. In-situ synchrotron diffraction was employed to measure time–temperature–load diffraction patterns. Calculations were made of the volume fractions of the phases, the transformation kinetics, and the austenite lattice parameter during cooling and simultaneous loading. In addition, volume fractions and lattice parameters of retained austenite at room temperature under different loading conditions were obtained. The results show that applying a load during cooling of the fcc phase significantly increases the volume fraction of a bcc phase before the start of the martensitic transformation. The kinetics of phase transformations were affected by the applied loads. The volume fraction and lattice parameter of retained austenite at room temperature vary in different samples and the highest retained austenite and the largest lattice parameter were obtained in the sample subjected to the highest load.Correction to article: https://doi.org/10.1007/s11661-017-4453-7 To reference this document use: http://resolver.tudelft.nl/uuid:e357453d-9f9c-4813-907b-6222cd50acb3 DOI https://doi.org/10.1007/s11661-017-4415-0 ISSN 1073-5623 Source Metallurgical and Materials Transactions A - Physical Metallurgy and Materials Science, 49 (1), 78-87 Bibliographical note + Correction to: In-Situ Synchrotron X-ray Diffraction Studies on Effects of Plastic and Elastic Loading on bcc Phase Transformations of a 3rd Generation 1 GPa Advanced High Strength Steel, 27 December 2017, https://doi.org/10.1007/s11661-017-4453-7 Part of collection Institutional Repository Document type journal article Rights © 2018 P.
