The microstructure and mechanical properties have a significant impact on the service performance of materials. This paper compared 2024 aluminum alloy subjected to turning ultrasonic surface rolling process (USRP). It was found that both USRP can cause grain refinement increased microhardness. induced by attributed dislocation proliferation T-phase fragmentation; At same time, quantitative relationship model between microhardness during constructed. results showed precipitation had greatest...
The fatigue load that a material experiences and its microstructure are important factors influencing crack propagation behavior. This study employed laser scanning microscopy electron backscatter diffraction (EBSD) technology, along with experiments, to investigate the behavior of 2024 aluminum alloy under varying stress ratios (R). results showed amplitude (σp) was main factor controlling life (N). Additionally, detailed characterization path conducted using crystal models EBSD. A model...
Laser Shock Peening (LSP) is a well-established surface treatment commonly used to improve mechanical properties of material's surfaces. To further understand the relationship between tensile property and fatigue life improvement high strength low alloy steel in LSP process, 32CrNi was carried out by YAG laser with pulse energy 15 J, tested electronic universal material testing machine. Surface morphology, residual stress fracture specimens before after were observed white light...
The ACK family tyrosine kinase SID-3 is involved in the endocytic uptake of double-stranded RNA. Here we identified as a previously unappreciated recycling regulator Caenorhabditis elegans intestine. RAB-10 effector EHBP-1 required for endosomal localization SID-3. Accordingly, animals with loss phenocopied defects observed ehbp-1 and rab-10 single mutants. Moreover, detected sequential protein interactions between EHBP-1, SID-3, NCK-1, DYN-1. In absence DYN-1 failed to localize at tubular...
Carbonation process of calcium-based sorbent, as a promising technique for CO2 capture, was examined in fixed-bed reactor. A method established to calculate the exact adsorption capacity using Non-Dispersive Infrared Radiation (NDIR) analyzer analytical unit. The factors affecting carbonation sorbent were investigated thoroughly. conversion and reached 65% 41%, respectively, when partial pressure 0.01 MPa at 600 °C, exhibiting an obvious advantage terms relatively low temperature. results...
To explore the evolution mechanism of multistage machining processes and torsional fatigue behaviour based on strain energy for first time provide process optimization axis parts low alloy steel service performance, four were applied to 45CrNiMoVA steel, including Rough Turning (RT), RT+ Finish (FRT), FRT+ Grinding (GFRT) dry cutting condition (FRT0). The result showed that FRT process's average low-cycle life increased by 50% when it evolved from RT process. lower surface roughness Ra 1.3...
Carbon dots (CDS) have been proved to be a type of ideal biological imaging probe. They the advantages spontaneous fluorescence, anti-photobleaching, good biocompatibility and easy surface decoration, are receiving special attention from researchers. The early diagnosis tumors has always practical means clinical diagnosis. Finding an efficient low-toxicity tumor probe is continuous goal treatment. Therefore, this article uses modifiable properties structure carbon dots, at same time,...
Abstract In this paper, a method for fault diagnosis in casing cutters is proposed. A vibration signal acquisition circuit use high-temperature environment was designed, and cutter measurement model established, including of the trouble-free state two other common states. The characteristics were analyzed. feature enhancement based on to noise ratio sparse representation, which effectively solves problem caused by limited installation location performance at high temperature, also designed....
High-performance manufacturing (HPM) is essential for high-quality equipment and parts manufacturing, which requires not only geometric accuracy but also control of surface integrity to satisfy functional performance. Surface topography residual stress are important elements integrity. However, they always investigated individually, their collaborative formation pattern has been ignored a long time. In this study, will be measured by 3D laser scanning microscope analyzed from the perspective...
This paper proposes the use of sleeve joints for steel connection concrete-filled, square, tubular columns to H-beams. To study influence height and thickness, three joint specimens were designed subjected low-cycle loading tests. The effect these size parameters is evaluated in terms specimen stiffness, load-bearing capacity, energy dissipation ductility performance shear deformation joint. experimental results show that under reciprocating load, ultimate failure modes are tearing at...
