This study explores the intricate interplay between strain-induced precipitation (SIP) and underlying mechanisms that govern hot deformation in AA6082 aluminum alloy. Uniaxial tensile tests were conducted at elevated temperatures, ranging from 200°C to 400°C, varied strain rates 0.01 s−1 10 s−1. Employing advanced methodologies such as scanning electron microscopy (SEM), backscatter diffraction (EBSD), energy dispersive X-ray spectrometry (EDS), transmission (TEM), research investigates...

Abstract The microstructure evolution during hot deformation of 80MnSi8-6 nanobainitic steel was investigated through compression tests at temperatures 900–1250°C and strain rates 0.1–20 s −1 . flow curves revealed strain-hardening behavior the beginning followed by softening effects caused evolution. A Johnson–Mehl–Avrami–Kolmogorov (JMAK) model for grain growth dynamic recrystallization developed, kinetics were determined. Critical peak strains identified, coefficients models determined...

Hot stamping of steel sheets using water or nitrogen cooling media was studied on a laboratory scale. Sheets grade 22MnB5 boron steels in three different thicknesses were investigated and the results experimental hot tests considered. Microstructural analysis, linear surface hardness profiling as well tensile formed samples carried out. After stamping, mostly fully martensitic microstructures, which yield ultra high strength levels, produced. It is concluded that die media, i.e., nitrogen,...

Abstract Electron backscatter diffraction (EBSD) and electron probe microanalysis (EPMA) measurements are combined to characterize an industrial produced dual-phase steel containing some bainite fraction. High-resolution carbon mappings acquired on a field emission microprobe utilized validate improve the identification of constituents (ferrite, martensite, bainite) performed by EBSD using image quality kernel average misorientation. The combination eliminates ambiguity between...

Metal additive manufacturing has strongly gained scientific and industrial importance during the last decades due to geometrical flexibility increased reliability of parts, as well reduced equipment costs. Within field metal methods, selective laser melting (SLM) is an eligible technique for production fully dense bulk material with complex geometry. In current study, we addressed application SLM processing a high-manganese TRansformation-/TWinning-Induced Plasticity (TRIP/TWIP) steel. The...
