The main purpose of this paper was to investigate the effect a surface plastic deformation layer introduced by multi-pass ultrasonic rolling (MUSR) on mechanical and fatigue properties HIP Ti-6Al-4V alloys. Some microscopic analysis methods (SEM, TEM XRD) were used characterize modified microstructure in material layer. results indicated that experienced certain extent deformation, accompanied some dense dislocations twin generation. Moreover, microhardness, residual stress roughness values...
Variations of stress and strain, from the riveting process through tensile loading stage in lap joints with a single countersunk rivet, were studied experimentally numerically. In situ microstrain gauges used to measure strain variations during entire sequence. Three-dimensional finite element (FE) models generated simulate experimental setup. The material elastoplastic constitutive relationship geometric nonlinear properties, as well contact boundary conditions, included numerical...
The accuracy and reliability of small-scale mechanical tests remain doubtful due to significant dependence the obtained properties on specimen size. Mesoscale tensile with sizes ranging from 10 μm 1 mm are capable obtaining bulk-like but rarely applied hexagonal close-packed metals. In this study, well-designed comparative were carried out a Zircaloy-4 alloy grain size 4 using femtosecond laser-machined mesoscale specimens thickness about 60 μm, sub-sized 1.3 mm, standard mm. quantitative...
Optical coatings deposited by the dual ion beam sputtering (DIBS) method usually show high compressive stress, which results in severe wavefront deformation of optical elements. Annealing post-treatment has been widely used to control residual stress coatings. However, effect annealing on Ta2O5 films IBS not reported detail. In this study, different thicknesses were and annealed at temperatures from 473 973 K air, was investigated. The as-deposited are about 160 MPa. decreases linearly with...
Using titanium, boron carbide and iron-based alloy powders as reactive sources, an Fe-based cladding coating reinforced by in situ synthesised TiC-TiN particles was fabricated using the plasma method. The effects of Ti B 4 C content on phase composition, microstructure, microhardness, wear resistance corrosion were studied. coatings composed α-Fe, Cr, Fe 3 C, TiC, TiN, 23 6 (C,B) . relative , layer increased with increase contents. hardness, content. results indicated that composite...
In order to investigate the dynamic splitting tensile strength of reactive powder concrete (RPC) under high strain rates, split Hopkinson pressure bar experiments are conducted on hybrid-fiber-reinforced (2% steel fiber and 0·2% polypropylene fiber) RPC. The results show that RPC increases with an increase in nominal rate from 100 350 s −1 . increasing factor (SDIF) is lower than ordinary same compressive strength. This mainly because compactness higher normal concrete. Further, considering...
