The Influence of Ni on Bainite/Martensite Transformation and Mechanical Properties of Deposited Metals Obtained from Metal-Cored Wire

Abstract: The multi-pass deposited metals were prepared by metal-cored wire with low (2.5 wt%) and high (4.0 wt%) Ni to research the effect of Ni on the bainite/martensite transformation. Results showed that deposited metals exhibited a multiphase structure comprised of bainite, martensite and residual austenite, which is not only explained from SEM/TEM, but also identified and quantified each phase from crystallographic structure through XRD and EBSD. With Ni content increasing, the fraction of martensite increases fro… Show more

“…The strength increases considerably with the cooling rate during quenching. By reducing the martensite transformation temperature and producing enormous martensite (high volume phase), nickel is a common austenite stabilizer which subsequently increases strength in an indirect manner [22]. Also, UTS can be strengthened using a substitusional solid solution.…”

“…Azimi et al [ 41 ] proposed a deep learning method for microstructure classification in the example of specific microstructural compositions of mild steel. However, most current research on maraging steels focused on a single variable for a particular grade [ 42 ]. Literature-based datasets and multi-algorithmic machine-learning modelling methods have yet to be devised.…”
