Phase transformations of the duplex stainless steel UNS S31803 under non-isothermal conditions

Journal of Materials Research and Technology, 2021
Precipitation of the intermetallic phases embrittles duplex stainless steels. Currently, most studies in this subject simulated aging phenomena by first holding the material at different isothermal conditions and then, quenching down under high cooling ...

Original ArticleComputer simulation in 3D of a phase transformation nucleated by simple sequential inhibition process

Journal of Materials Research and Technology, 2020
Analytical and numerical models of nucleation and growth transformations usually suppose that nuclei are located uniform randomly, i.e., according to a Poisson point process, within the matrix.
