Springback prediction and validation in hot forming of a double-curved component in alloy 718

Abstract The demands associated with the production of advanced parts made nickel-base superalloys are continuously increasing to meet requirements current environmental laws. use lightweight components in load-carrying aero-engine structures has potential significantly reduce fuel consumption and greenhouse gas emissions. Furthermore, competitiveness industry can benefit from reduced costs shorter development times while minimizing costly try-outs efficiency engines. manufacturing process at temperatures close 950 °C produces stamping force, residual stresses, springback compared traditional forming procedures occurring room temperature. In this work, a hot procedure double-curved component alloy 718 is studied. mechanical properties material determined between 20 1000 °C. presence nature serrations stress–strain curves assessed. novel version anisotropic Barlat Yld2000-2D model, which allows input thermo-mechanical data, used LS-DYNA model behaviour high temperatures. effect considering stress-relaxation data on predicted shape distortions evaluated. results show importance predict final geometry accuracy. implementation models finite element (FE) analyses, along precise conditions, vital produce materials interest aerospace industry.
