This study investigates the deformation characteristics of a ring-stiffened cylindrical shell induced by shock waves and coalesced bubbles in double-charge underwater explosions. A numerical model for coupling multi-point explosion loads with is established Arbitrary Lagrange Euler method, experiments double charges are also conducted. The model's effectiveness validated comparing wave superposition characteristics, bubble coalescence processes, pulsation periods experimental results. Based...
Multilayer metal composites based on dissimilar metals and alloys have great application value for many industries key equipment because of excellent comprehensive properties. In this work, the AA1060/TA2/SS30408 trimetallic were successfully prepared by explosive welding technology. The 2D 3D interface microstructure characterized using field emission scanning electron microscope (FSEM) computer tomography (CT). Meanwhile, to revel phase constitution two joining interfaces, backscatter...
To improve the protective performance of structures in terms explosive shock waves and fragment penetration, a foamed aluminum/UHMWPE fiber sandwich composite structure was designed. A "explosion+fragmentation" penetration experiment used to study failure mode mechanisms materials, effects core material combination explosion distance were discussed, meanwhile, numerical simulation using LS-DYNA adopted simulate timing distribution law wave fragments. The results show that is main influencing...
This work aims to produce a thorough comprehension concerning microstructure related properties of the joint interface between Ta foil and steel plate fabricated by explosive welding. For this, self-developed welding configuration was employed join plate, different microscopic methods were adopted investigate its microstructures mechanical properties. It found that Ta/Fe featured regular wavy structures with well-defined amplitude period. The melted zones mainly observed within vortex...
Obtaining high-quality Pt coatings remains a challenging task. Here, explosive welding was attempted to prepare on steel plate, and the complex interfacial phenomena of achieved Pt/Fe joints as well governing mechanisms were carefully investigated by multi-scale microstructure analyses smoothed particles hydrodynamics simulations. The results demonstrated that self-development suitable method for preparing coatings, featuring desirable undulating metallurgical interface. Two types transition...
Cobalt has a reputation for its excellent electrical and magnetic properties, exceptional wear corrosion resistance, which many applications in the batteries, electronic industry semiconductor industry. In this work, explosive welding technique was successfully performed to join Co/Cu dissimilar metals. To reveal phase constitution texture distribution of vortex zone at joining interface, electron backscatter diffraction (EBSD) test carried out. It concluded that typical structure composed...
Mass spectrometry imaging (MSI) collects mass spectra of organic compounds from individual micrometer-sized spots and yields high-resolution images the spatial distribution target analytes on sample surfaces. MSI can potentially open a new avenue to ultra-high resolution molecular stratigraphy by resolving fine-scale biomarkers in geological records. However, ionization molecules within their sediment matrix remains critical challenge. Building recent introduction archaeal tetraether lipids,...
