| Abstract Scope |
The formability of metallic alloys is a critical factor in their application in aerospace, biomedical, and automotive industries. For sheet metals like Ti-6Al-4V, accurate prediction of forming limits is essential to optimize manufacturing processes and reduce material waste. Ti-6Al-4V, a dual-phase alloy, exhibits significant anisotropy and complex deformation behavior.
This work integrates experimental microstructural characterization with crystal plasticity simulations to build a physically informed forming limit diagram (FLD) for Ti-6Al-4V. Electron Backscatter Diffraction (EBSD) and X-ray Diffraction (XRD) are used to determine grain morphology, crystallographic texture, and phase distribution. These microstructural inputs are essential for use in models capable of capturing the anisotropic plastic response of the alloy.
Advanced characterization of microstructural features is important in obtaining reasonable results. The approach described here provides a mechanistically grounded pathway for predicting the formability of complex alloys and supports the development of microstructure-sensitive forming simulations. |
