Influence of Y₂O₃ Content on Microstructure and Properties of Laser Alloying WC/Ni Metal Ceramic on 38CrMoAl Steel

Cailiao gongcheng, 2017
WC/Ni reinforced layers with different Y2O3 contents were fabricated on the surface of 38CrMoAl steel by laser alloying. The influence of Y2O3 content on the phase composition, microstructure, microhardness and tribological performance of the alloying ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

High sensitivity and detectivity of anomalous Hall sensor based on coupled magnetic bilayers

AIP Advances
Detection of ultralow magnetic field requires a magnetic sensor with high sensitivity and a low noise level. In this work, we used the Co20Fe60B20/Ti/Co20Fe60B20 magnetically coupled multilayer as the core structure of an anomalous Hall sensor.

Electron beam calibration constants

Japanese Journal of Radiological Technology, 1978
Electron treatment beam calibration constants are tabulated in a convenient form for mean incident electron energies, Eo, of 6 to 21 MeV; and practical reanges, Rp, of 2.75 to 10.53 cm of water. Values of mean electron energy at depth Ed, chamber radius correction factors (Kp), and CE factors may be readily obtained from this chart.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Experimental and simulation study of helium plasma transport during ion cyclotron resonance heating in MPS-LD

Nuclear Fusion
The linear plasma devices (LPDs) can provide a good platform to experimentally simulate the divertor physics. MPS-LD is a new LPD, which uses ion cyclotron resonance heating (ICRH) to raise the ion temperature ( T _i ).
