Abstract Scope 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 relatively high manufacturing cost still 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 rapidly mapping using the high-throughput combinatorial methods. The compositionally graded sample manufactured using different techniques were firstly studied using SEM EDS. Nanostructures including omega phase, O’ phase and incommensurate domains were characterized using diffraction contrast TEM. The properties, such as hardness and modulus, for different compositions were evaluated using high-throughput nanoindentation technique. This work is supported by the National Science Foundation, grant CMMI-2122272 and DMR-2145844.
