Improving the application of nanomaterials has always been a research hotspot in field energetic materials (EMs) due to their obvious catalytic effect on EMs, especially uniformly dispersed nanomaterials. However, few studies have reported dispersion In this study, dispersity and mixing uniformity nano-CuCr2O4 was evaluated based difference solid UV light absorption between nano-catalytic EMs. The nano-CuCr2O4/ultrafine AP composites with different were prepared by manual grinding mechanical...
Abstract An approach based on the local stress response is proposed to locate fatigue critical point for metallic blunt notched specimens under multiaxial loading. According analysis, both gradient and of loading nonproportionality exist at notch root. The plane in vicinity that passes through experiences maximum shear amplitude defined as (CPN). Furthermore, Susmel's damage parameter modified assess life components by combining CPN theory distance (TCD). test thin‐walled round tube made...
This study delves into the impact toughness of medium-thick (12 mm thick) titanium alloy joints crafted through a multi-layer, multi-pass welding technique that blends laser-arc (MIG) hybrid technology. Microstructural scrutiny, employing optical microscopy, SEM and TEM, unveils consistent composition across weld passes, with prevailing α/α′ phases interspersed some β phase, resulting in basket-weave structures primarily dominated by acicular α′ martensite. However, upper regions exhibit...
Ammonium perchlorate (AP) is a commonly used oxidant for solid propellants, and improving the thermal decomposition performance of AP has been focus research, as its directly affects propellant. Among variety catalysts, nanocomposite metal oxides have demonstrated significant role in facilitating AP. In this study, Cu-Cr-Fe ternary with different molar ratios (5:2:8, 5:4:6, 5:6:4, 5:8:2) were prepared by facile mechanical grinding method to investigate their catalytic effect on properties...
The plasma sprayed Fe-based Ni/WC composite coating on the surface of 45 steel was post-treated by laser remelting with addition nano-SiC. effect power interface microstructure a nano-SiC modified coatings were researched. metallographic structure, microscopic morphology, phase composition, and microhardness remelted layer visually analyzed microscope, scanning electron microscope (SEM), X-ray diffractometer (XRD), tester, respectively. results showed that smooth compact, no fine cracks....
The recycling value of chips pure alpha-Ti was demonstrated with eco-friendly equal channel angular pressing (ECAP) to replace energy intensive melting and casting. Electron backscatter diffraction (EBSD) used reveal the microstructure formed after single- or multi-pass ECAP, characterized by a heterogeneous structure containing high- low-angle grain boundaries (HAGBs, misorientation ≥15°, LAGBs, <15°). Grain formation analyzed considering shear strain due tooling features ECAP die, thermal...
Understanding the fluid pattern is of special significance for estimating hydraulic conductivity fractured rock masses. The nonlinearity flow in discrete fracture networks (DFNs) originates from inertial effects and enhanced by complex geometric topologies, which produces additional viscous friction subject to inertia effects, consequently transitioning nonlinear regime. Therefore, it important obtain critical conditions transition a laminar turbulent flow. To investigate role aperture...
Rock fracture morphology influences two-phase fluids flow in rock fractures. However, the role of surface fractures on fluid has been properly quantified yet. Quantifying with roughness factor, hydraulic tortuosity and an analytical model for gas-water relative permeability rough is developed. The performance proposed was evaluated empirical models, natural artificial experiment data. results show that described characteristics With model, influence dynamic distribution further investigated....
