Microstructure and Crystallographic Texture Evolution in Dual-Phase High-Mn Low-Density Steel during Homogenization
摘要
Despite the importance of low-density steels, the evolution of crystallographic texture in Al-Si-added high-Mn steels has received little attention, particularly the role of initial texture before thermo-mechanical processing in steels containing two phases. The present study aims to bridge this gap by investigating the evolution of microstructure and texture in low-density high-Mn steels during homogenization. Two steels, S1-H (12Al-2Si) and S2-H (9Al-0.2Si), were fabricated using the melting-casting method, followed by a homogenization treatment to minimize chemical inhomogeneity. Microstructural characterization using a scanning electron microscope with energy-dispersive x-ray spectroscopy (SEM-EDS) revealed the presence of
