Abstract
This study investigated the effects of a hot forging process on homogenizing the microstructure and enhancing the mechanical properties of high manganese steel (Fe-24M3n-3Cr-0.7Si-0.5C-0.4Cu wt%) cast specimens. Cast specimens exhibited coarse-grained microstructures with average grain sizes about 900 μm, significant elemental segregation of Mn and Cr in interdendritic regions, and..... More

Abstract
In this study, the Vickers hardness of precipitation-strengthened Al-Sc-X (X = Zr, Si, and Fe) alloys were predicted using machine learning models, depending on the alloys’ compositions, solid-solution treatment and aging conditions. The data used for machine learning were collected from the literature. Among the models, tree-based ensemble models such..... More
