Abstract The deformation microstructure of austenitic Fe-18Cr-(10-12)Ni (wt pct) alloys with low stacking fault energies, estimated by first-principles calculations, was investigated after cold rolling. ɛ -martensite found to play a key role in the nucleation α ′-martensite, and at SFE, formation is frequent facilitates ′ individual shear bands, whereas band intersections become dominant sites for when SFE increases mechanical twinning becomes frequent.
Abstract Nanostructure evolution during low temperature aging of three binary Fe-Cr alloys has been investigated by atom probe tomography. A new method based on radial distribution function (RDF) analysis to quantify the composition wavelength and amplitude spinodal decomposition is proposed. Wavelengths estimated from RDF have a power-law type are in reasonable agreement with wavelengths using other more conventional methods. The main advantages proposed following: (1) Selecting box size...
Additive Manufacturing (AM) is becoming an important technology for manufacturing of metallic materials. Laser-Powder Bed Fusion (L-PBF), Electron beam-Powder (E-PBF) and Directed Energy Deposition (DED) have attracted significant interest from both the scientific community industry since these technologies offer great opportunities niche applications complex geometries. Understanding physics behind dynamic phenomena occurring during processes essential overcoming barriers that constrain...
To enhance the fundamental understanding for micromechanical lath martensite deformation, microstructure as well macro- and microscopic tensile properties of as-quenched 15–5 PH stainless steel are systematically analysed depending on austenitisation temperature. Based electron backscatter diffraction (EBSD) backscattered (BSE) analysis, it is noted that morphology alters from a less defined to more clearly parallel arrangement block structure with increasing For an in-depth quantification...
Abstract The martensite start temperature ( M s ) is a critical parameter when designing high-performance steels and their heat treatments. It has, therefore, attracted significant interest over the years. Numerous methodologies, such as thermodynamics-based, linear regression artificial neural network (ANN) modeling, have been applied. application of data-driven approaches, ANN or wider concept machine learning (ML), shown limited technical applicability, but considering that these methods...
The solidification and microstructural evolution during deposition, as well the structural post heat treatment, determine mechanical properties of wire-arc additively manufactured maraging stainless steels. In present work, we tune austenite reversion nanoscale precipitation treatment achieve an excellent combination strength ductility (ultimate tensile ~1340 MPa uniform elongation ~10.5 %). is studied through computational thermodynamics, electron microscopy, in situ small-angle neutron...
In this study, we investigate the relation between microstructure and fatigue crack propagation mechanisms in three commercial hot-rolled thick-plate advanced high-strength steels (AHSSs), namely 800CP, 700MC, 700MCPlus, compare them with a conventional low-alloy (HSLA) steel, 500MC, commonly used heavy-duty vehicle chassis production. Tensile testing, growth rate (FCGR) assessments have been conducted, controlling performance of these are comprehensively examined through characterization...
