The mechanical properties and serviceability of the alloy fabricated by laser powder bed fusion (L-PBF) additive manufacturing (AM) strongly depend on phase composition microstructure, which are affected thermal condition process, such us cooling rate. In this study, AlCrFe2Ni2 medium entropy (MEA) was L-PBF under varying rate via changing process parameters. transformation, microstructure were experimentally investigated using X-ray diffraction (XRD), scanning transmission electron...
Medical images often exhibit intricate structures, inhomogeneous intensity, significant noise and blurred edges, presenting challenges for medical image segmentation. Several segmentation algorithms grounded in mathematics, computer science, domains have been proposed to address this matter; nevertheless, there is still considerable scope improvement. This paper proposes a novel adaptive anatomical structure-based two-layer level set framework (AS2LS) segmenting organs with concentric such...
Abstract The unique high-temperature properties of refractory high entropy alloys (HEAs) are mainly depended on their phase formation. Therefore, a new approach to predict the formation has be proposed, in order accelerate development HEAs. Here, we use machine learning build classifiers Our dataset containing 271 data only consists as-cast HEAs data. We simplify input parameters element content, and refine outputs into five classes. Decision tree been employed our classifier, due its great...
Various incentives in the smart grid, which force power consumer to take respond demand and change characteristics of load, will affect load forecasting. In this paper, it is concluded that spatial-temporal distribution are relevant impact considered forecasting model. It sifted multivariate series highly prediction point with correlation analysis, modeled from viewpoint time long short-term memory (LSTM). By comparing artificial neural network support vector machine, verified model proposed...
Electro-deposition is more commonly used as a method of copper surface treatment. Cu2+ concentration, current density and electro-deposition time play important roles in deposition mass. In this paper, the influence on Cu mass was studied through regressive orthogonal experiment. The results show that have linear positive correlation cross-effects
Abstract With the development of hypersonic vehicle, design heat-resistant and load-bearing surface vehicle has gradually become a key technology affecting its combat effectiveness. As new type lightweight high-strength structure, lattice structure excellent mechanical properties such as ultra-light, high specific strength stiffness, special vibration reduction, heat dissipation sound absorption. Among them, multi-level can increase bearing efficiency at low relative density, transfer area...
Deep-penetration welding of nickel-based superalloys is an indispensable manufacturing technique for aircraft engines, aerospace and nuclear containers. In this study, a newly developed vacuum laser beam method was used to weld 9 mm thick superalloy 718Plus. A defect-free complete joint penetration with high depth-to-width ratio fabricated. The macro/microstructures, microhardness, tensile properties, fatigue properties joints under both as-welded heat-treated conditions were systematically...
High-entropy alloys (HEAs) with ultrafine grained and high strength can be prepared by mechanical alloying (MA) followed sintering. Therefore, MA, as a unique solid powder processing method, has many effects on the microstructures properties of sintered bulk HEAs. This work focused behavior, morphology, phase evolution FexCrNiAl (x = 1.0, 0.5, 0.25) HEAs MA. The X-ray diffraction results show that powders achieved supersaturated solution body-centered-cubic (BCC) after MA; crystalline size...
Dilute magnetic semiconductors (DMSs), such as (In, Mn)As and (Ga, prototypes, are limited to III–V with Curie temperatures ( T c ) far from room temperature, thereby hindering their wide application. Here, one kind of DMS based on perovskite niobates is reported. BaM x Nb (1− O 3− δ M = Fe, Co) powders prepared by the composite-hydroxide-mediated method. The addition elements endows local ferromagnetism. tetragonal BaCo nanocrystals can be obtained Co doping, which shows strong saturation...
The looper system in hot strip mills has the features of nonlinearity, strong coupling and uncertainty. To improve accuracy quality control, A new multivariable decoupling control is proposed this paper, which consists diagonally matrix method-based decomposition compensatory unit sliding mode controller (SMC). Simulation experiments for conventional were conducted using MATLAB/Simulink software, simulation results show effectiveness controllers compared with ones.
