The tube numerical control (NC) bending process is a much complex physical with multifactors coupling interactive effects. mandrel the key to improve forming quality and enhance limit. In this study, based on platform of ABAQUS/Explicit, 3D elastic-plastic finite element model NC 2169 (0Cr21Ni6Mn9N) stainless steel was established, technological problems were solved, its reliability validated. Then, simulation analysis processes carried out, influence laws types parameters cross-section...
In order to investigate the mechanical behavior of a novel pre-tensioned polygonal prestressed T-beam subject combined bending, shear, and torsion, this study meticulously designed fabricated full-scale specimen with calculated span 28.28 m, beam height 1.8 top flange width 1.75 m. A systematic static loading test was conducted. multi-source data acquisition methodology employed throughout experiment. variety embedded external sensors were strategically arranged, in conjunction non-contact...
In this paper, wire-feed electron beam additive manufacturing (WFEBAM) was utilized to repair the damaged Ti6Al4V (abbreviated as Ti64) alloy with B and Y modified Ti64 wire, effect of heat input on repaired microstructure properties investigated. The results indicated that sizes prior columnar β grains α laths increased gradually input. Besides fine acicular laths, continuous αGB, retained phase, bits needle-like TiB Y2O3 nanoparticles were formed in deposited zone (DZ) due addition...
The interdiffusion behaviours and oxidation resistance of the NiCrAlY/Al duplex coated specimens during isothermal test at 950°C were investigated. It was shown that NiCrAlY coating system with an Al bondcoat outperformed single substrate γ-TiAl alloy hot exposure. Analysis techniques such as X-ray diffraction, scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS) used to study phase formation, microstructure depth distribution elements in specimens. results showed...
The mechanical properties of FeAl and ternary Fe–X–Al (X = Cr, Mo) alloys are investigated using first-principles density functional theory (DFT), with the valence electron structures also being determined empirical solids molecules. structural attributes fitted an E–V curve, stable systematically predicted along their respective elastic constants phonon frequencies. bonding nature in is partly defined by covalence orbital hybridization, which explains its intrinsic brittleness....
Abstract This paper investigates the dynamic recrystallization characteristics of SAE52100 large section bearing steel under hot compression, focusing on both center and surface. Using data from thermal simulation experiments physical models were developed. Four machine learning algorithms including support vector regression, k‐nearest neighbors, random forest, extreme gradient boosting then employed to develop prediction based experimental inferred values model. The results show that...
Adding modified elements to regulate the microstructure of titanium alloys prepared by additive manufacturing and enhance mechanical properties as-deposited has become a research focus. However, this approach also brings risk causing materials with high strength-low plasticity characteristics. In study, macroscopic layered structure alloy hierarchical heterogeneous characteristics was constructed alternately melting Ti6Al4V wire Cu-modified using electron beam as heat source. The tensile...
A maritime target detection method based on improved YOLOv7 is proposed to address the problems of low accuracy and poor timeliness caused by interference complex ocean environment variable scale be measured. Firstly, a global context module (GC-model) introduced in backbone part improve localization for key feature information situations. Secondly, an SA-BiFPN network structure designed replace path aggregation (PAN) speed up flow rate information, finally, VarifocalLoss optimize binary...
