Due to the combination of great properties, such as high strength, low density and excellent corrosion resistance, titanium alloys have become a good candidate for structural materials in aerospace, chemical and bio-medical industries. However, the high manufacturing cost limits the wide application of titanium alloys. Thus, it still requires significant effort in designing novel low-cost titanium alloys with great performance. In this work, the inter-relationship between composition, microstructure and properties in Ti-X (X=Mo or Fe) alloys were systematically studied using the high-throughput combinatorial methods. Nanostructures including omega phase, O’ phase and incommensurate domains were characterized in Ti-X alloys using diffraction contrast conventional TEM and Z-contrast aberration-corrected STEM. Phase transformations including isothermal omega phase and alpha phase were studied in Ti-X alloys. The properties, such as hardness and modulus, for different compositions were evaluated using high-throughput nanoindentation technique. |
