Molecular Dynamic (MD) simulations were used to investigate the tensile properties of nanocrystalline Ni–Al series Ni-based superalloy at different grain sizes (6.54–20 nm), strain rates (1 × 107–5 108 s−1) and temperatures (300–1000 K). Results indicate that plastic deformation was governed by stacking faults FCC-to-HCP martensitic phase transformation, which significantly from twinning-dominated in Ni. Nevertheless, conventional Hall-Petch breakdown occurred a critical size both Ni...
This study aims to present the optimum technological parameters of hot forging process aerospace bolts. Deformation-related were determined according relevant conditions for commercial production Deformation behavior and evolution microstructure Waspaloy systematically studied at temperature in range 1000–1120 °C strain rate 0.01–10 s−1. The obtained results revealed sensitivity flow stresses deformation increased when deformed lower temperatures or higher rates. At high rates 5–10 s−1,...
Effects of aging and thermal cycling on the microstructure damping behaviors a porous CuAlMn shape memory alloy (SMA) were studied. It was found that with increasing temperature intensity internal friction peak initially increased, followed by decrease in reverse martensitic transformation. In addition, position shifted from low to high temperature. This phenomenon has been ascribed refinement laths as well annihilation quenched-in vacancies. The process also influence SMA. For instance,...
Cold metal transfer arc additive manufacturing technique was used to produce 5356 aluminum alloy by adding refining agents solve the problems of coarse grains and poor performance. Metallic powders (Ti, TiH, Ti+B
Abstract Al–Li alloy has been widely used in the aerospace field owing to its high strength and low density. In this study, alternating current cold metal transfer (AC CMT) along with a high-frequency pulse technique was weld 2060 using an ER5356 wire. The effect of frequency on arc shape, microstructure, mechanical properties welded joints examined, performance testing conducted. results revealed that diameter, length, volume showed trend increasing first then decreasing increase reached...
In this study, the effect of homogenization treatments (single and double stages) on wire + arc additively manufactured (WAAM) 2319 Al alloy was analyzed. This involved an in-depth study diffusion dissolution eutectic phases using advanced characterization techniques (DSC, XRD, optical electron microscopy). Homogenization treatment parameters (temperature time) were determined based DSC analyses. These later confirmed kinetics calculations. A single-stage at 530℃/24h facilitated a full Al2Cu...
Nickel (Ni)-based single-crystal superalloys are of great importance in the aircraft industry due to their excellent mechanical properties, and cracks as unavoidable defects may affect performances materials dramatically. In this paper, large scale molecular dynamics (MD) simulations carried out understand deformation mechanisms Ni-based single crystal with a central crack under tension. Here, effects matrixes (g, g′ g/g′), strain rates (1×109 s-1 ~ 3×109 s-1) temperatures (300 K~ 900 K) on...
Evolution of microstructure and creep properties Inconel 718 alloy under different temperatures stresses were studied comprehensively. Mechanisms fracture was investigated a model for also developed. Results reveal the coarsening γ″ phase its transformation into δ when exposed above 650 ℃. The governed by Nb diffusion in matrix. area fraction increased as progressed. In addition, steady state rate life decreased, with an increase temperature stress. Longer holding times at high stress can...
In this study, a strip-shaped Al–5Ti–1B grain refiner was employed to produce Al–Mg alloy using cold metal transfer arc additive manufacturing. The microstructure and mechanical properties of the straight-wall samples (SWSs) were analyzed. results indicated that Al3 Ti phase occurred in SWS with Al–5Ti–1B, acted as heterogeneous nucleation site during solidification. formation particles led transformation columnar grains between layers into equiaxed refined at center layers. Furthermore, Al...
