Abstract A 10 mm narrow gap TC4 titanium alloy welded joint by laser welding with filler wire was obtained different heat inputs. The microstructures of the were analyzed OM, SEM, XRD and EBSD. mechanical properties microhardness test tensile test. results show that increase input, average grain size width equiaxed crystal zone in center weld increases, angle columnar gradually tends to be perpendicular weld, affected (HAZ) increases without obvious coarsening. HAZ is softened, its value...
Aluminium matrix composites reinforced with homogeneously dispersed graphene (Gr/Al) were fabricated by electrostatic self-assembly and powder metallurgy. The microstructure of the was observed. effects content, applied load sliding speed on tribological properties also investigated. results show that is in aluminium matrix. coefficient friction for initially increases later decreases increasing content. It lowest 0.3 wt-% Gr/Al composite, which a decrease approximately 20% when compared to...
The effects of silicon (Si) on the mechanical properties and fracture toughness heavy-section ductile cast iron were investigated to develop material for spent-nuclear-fuel containers. Two castings with different Si contents 1.78 wt.% 2.74 prepared. Four positions in from edge center, solidification cooling rates, chosen microstructure observation properties’ testing. Results show that tensile strength, elongation, impact at two decrease rate. With an increase content, graphite morphology...
Aluminum borate whiskers (ABOw) with or without ZnAl2O4 coating reinforced pure aluminum composites (ABOw/Al, ABOw/ZnAl2O4/Al) were fabricated by squeeze casting. The effects of on the compressive behaviors, microstructures, and matrix textures investigated at different temperatures strain rates. results indicate that maximum flow stress almost linearly decreases increase in temperature. ABOw/ZnAl2O4/Al composite is higher than ABOw/Al same temperature when rate larger, however, it reversed...
ZnO was firstly coated on the surface of aluminum borate whiskers (ABOw) by sol–gel. Then, ZnO-coated ABOw added into soybean slurry to make a preform with low volume fraction and sintered at high temperatures obtain sufficient strength. reinforced composite (ABOw/Al) fabricated squeeze casting. Interfacial microstructures, tensile properties, fracture mechanisms ABOw/Al were investigated. The results show that coating addition sacrificial filler can effectively decrease in composite....
A 20 mm thick TC4 titanium alloy plate was welded by ultranarrow gap laser welding with filler wire Ar and He as shielding gas, respectively. characterization analysis of the microstructures mechanical properties joint conducted OM, SEM, XRD, EBSD through microhardness test tensile test. The results showed that HAZ formed gas much wider than He, weld microstructure composition two gases basically consistent; phase boundary metal obtained clearer, a larger misorientation between laths; α ′...
TiB powders with submicrometer size were synthesized by mechanical alloying (MA) the mixture of elemental Ti and B in argon atmosphere using vibration ball mill. The ball-to-powder weight ratio was 10:1. phase transition morphology during MA investigated. Amorphization occurred after milling for 10h, which cubic formed keep stable until end.
The stability and reliability of wireless data transmission in vehicular networks face significant challenges due to the high dynamics path loss caused by complexity rapidly changing environments. This paper proposes a multi-modal environmental sensing-based prediction architecture (MES-PLA) for V2I communications. First, we establish environment channel joint acquisition platform generate spatio-temporally synchronized aligned dataset data. Then designed feature extraction fusion network...
