Inconel 625 alloy cladding layer was prepared by high-speed laser (HLC) on Q245R steel substrate to improve the service performance of structural components in power industry this work. A comprehensive study HLC coating with different scanning speeds conducted utilizing Scanning Electron Microscope (SEM), Transmission (TEM), Laser Confocal (LSCM), X-Ray Diffraction (XRD), a microhardness tester, and an SRV-4 high-temperature friction wear testing machine. The results show that layer's...
The room-temperature strength of Al0.3CoCrFeNi high-entropy alloys (HEAs) is relatively low owing to its intrinsic fcc structure. In the present study, as-cast HEAs were subjected cold rolling and subsequent annealing treatment (800, 900, 1000 °C) adjust microstructures tensile properties. This process resulted in partial recrystallization, full grain coarsening with increasing temperature. It was found that large spherical B2 precipitates generated recrystallized boundaries three states,...
ABSTRACT The low cycle fatigue (LCF) behavior and stress–strain responses of ultra‐pure 26Cr2Ni4MoV steel were studied under symmetric strain/stress‐controlled cycling ( R = −1) at room temperature. characteristic features cyclic stages—saturation, stable descent, rapid descent—were identified in both loading modes. Additionally, tension–compression asymmetry (TCA) significantly affected resistance, with ratcheting strain stress‐controlled reducing the life. In contrast, strain‐controlled...
Here, an electron beam selective melting (EBM) technique was employed to shape Ti-48Al-2Cr-2Nb alloy combat its intrinsic brittleness and insufficient hot workability. Through process optimization, high-density samples (4.2327 g/cm3) were produced. First, the mechanism of interaction between phase transformation microstructural evolution EBM-formed investigated using scanning microscopy (SEM), X-ray diffraction (XRD), backscattering (EBSD). And then, tensile properties discussed. Based on...
Abstract Finite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress cracking (SCC). Flat and U-shaped edge-notched specimens investigated terms CPF-induced metallic substrate CPF. For a specimen, field front notch tip is affected by Young’s modulus CPF thickness geometry. The tensile superimposed on applied load increase crack strain facilitate localized plasticity deformation. In addition, surface contributes rupture CPFs. results provide physical...
