Plastically deformed low-carbon steel has been analyzed by nondestructive three-dimensional orientation and strain mapping using scanning X-ray diffraction microscopy (S3DXRD). However, the application of S3DXRD is limited to single-phase alloys. In this study, we propose a modified analysis for dual-phase alloys, such as ferrite–pearlite carbon steel, which composed grains detectable spots pha...

This study investigated the true stress (σ)–true strain (ε) relationship up to plastic deformation limit in ferrite–pearlite (FP) steel at various temperatures. We found that a decrease temperature resulted an increase lower yield strength (LYS) and tensile (TS), both uniform total elongations. When was increased from 673 773 K, TS elongations decreased due blue brittleness. In σ–ε of FP temper...

High-carbon steels have been used to high-strength steel wire and strands for prestressing concrete. The necessity of levels at increasingly larger diameters rods is a technological challenge. Two with without Nb were obtained in mill, submitted detailed microstructural (previous austenitic grain size, pearlite interlamellar spacing colony size) mechanical characterization through tensile tests...

Microstructural banding is defined as alternating layers of two different microstructures in steel, often ferrite and pearlite. It is caused by fluctuations in the concentration of alloying elements, primarily manganese, due to microsegregation introduced during solidification. In this thesis, a model is presented to simulate banding using phase transformation kinetics theory. An existing progr...
