In this study, the effects of heat treatment on microstructure and mechanical properties extruded 2196 Al-Cu-Li alloy were examined precipitation behavior strengthening mechanism investigated. It was found that solution artificial aging had a significant effect alloy, which related to type, size, number density, distribution precipitates. Most second phases dissolved back into matrix after treatment. The sequence during identified as: supersaturated solid solution→ GP zone + δ′/β′...
In this study, a composite coating comprising ceramic film and layered double hydroxide (LDHs) layer was prepared on the surface of extruded 2195 Al–Li alloy. The preparation method, morphology, chemical composition were described characterized in detail. corrosion wear protection alloy substrate tested, mechanisms resistance discussed. results indicate that plasma electrolytic oxidation processing can form thick with good interface bonding Hydrothermal reaction an alkaline solution produces...
The effects of re-solution (RST) and re-aging (RA) treatment on the mechanical property, microstructure, corrosion resistance electrochemical behavior 2196 Al-Cu-Li alloy were investigated by tensile testing, conductivity intergranular testing. results show that RST RA can improve without sacrificing strength compared to T6 temper. aging precipitation process is reversible, number distribution δ', T1 θ' precipitates be effectively regulated treatment, so approximately reaches level temper...
Biodegradable calcium phosphate (CaP) ceramic coatings were prepared on self-designed Mg-2.0Zn-0.6Ca-xSi alloys by plasma electrolytic oxidation (PEO). The effect of (Ca) and silicon (Si) alloy microstructure coating formation biomineralization mechanisms discussed. in vitro bioactivity degradability CaP evaluated immersion tests simulated body fluid (SBF) solutions trishydroxymethyl-aminomethane hydrochloric acid (Tris-HCl) buffer, respectively. chemical composition the coatings,...
To obtain profiles with sound weld seams, the effects of extrusion parameters and heat treatment on microstructures mechanical properties seam were revealed. It was found that high speed increases welding quality area. The micro-voids formed in low temperature could hinder grains from growing through interface during treatment, which caused weak bonding seam. Lots strengthening phases precipitated aging leads to disappearance softened area improvement tensile strength. However, fine...
The aluminum alloy components on automobile often experience high strain rate deformation during accidents. dynamic behavior and constitutive model are crucial for analysis of vehicle body collisions failures. In this work, the 7A75 plate was heat treated according to standard manufacturing procedures. Quasi-static tensile experiments were conducted aged in a wide range from 0.001 s-1 500 s-1. revealed, models established. It found that has strong sensitivity, its mechanical properties can...
Abnormal grain growth (AGG) at longitudinal weld of 2196 AlCuLi profile was observed during solution treatment, and the effects AGG on aging behavior mechanical properties were investigated. The results show that area almost contained no low angle boundaries (LAGBs) while fine extrusion fibers in matrix numerous LAGBs. structure seam leads to precipitated phases coarsening, PFZ widening a sharp decrease elongation profiles. During process, more coarse S′/S T2 exhibited faster age hardening...
The spray deposited alloys need to be first extruded reduce porosity, and then the extrusion is conducted again for final profile forming. It required carry out an inter-annealing between two stages of extrusion. In this study, billets after were annealed with different parameters, effect annealing process on microstructure was investigated. Then obtain plates. role processes properties plates investigated through characterization mechanical testing. results show that increase width fibers...
