| Abstract Scope |
Titanium (Ti) alloys are ubiquitous in the aerospace, defense, and biomedical industries. Today, state-of-the-art characterization techniques available in the laboratory and at national user facilities are enabling unprecedented, multiscale in-situ/ex-situ studies of Ti alloys and new insights into processing-microstructure-property-performance relationships. Multiscale characterization of Ti-6Al-4V built by additive manufacturing (AM) reveals alpha-phase texture changes with scan strategy, typical {001} solidification texture revealed by beta-phase reconstruction, and varying (cube and fiber) beta-phase textures and grain morphologies produced by raster (large columnar grains) and spot (finer columnar and globular grains) melt strategies, linking processing to microstructure evolution and revealing possible strategies for microstructure and property control during AM. We also explore the role of omega-phase and transformation- and twinning-induced plasticity, or TRIP/TWIP, on the mechanical response of metastable Ti alloys after/during quasi-static or dynamic testing. These deformation mechanisms can be tailored to design properties and performance of Ti alloys for engineering applications. |
