Understanding phase selection during non-equilbirum processing of alloys requires combinatorial synthesis and high-throughput characterization techniques to sample the vast amount of phase space. Using the Ni-Nb binary alloy as a model system, we have synthesizing combinatorial libraries via magnetron sputtering and additive manufacturing using Laser Engineered Net Shaping (LENS). Using the thin film libraries, we have examined the glass forming ability and phase selection as a function of composition during devitrification using high-throughput synchrotron X-ray diffraction. Additionally, we have examined the solidification behavior of the different phases during non-equilibrium processing by utilizing laser remelting of the bulk combinatorial libraries (i.e., 3D printed). Using this integrated thin film and bulk combinatorial approach, we discuss how these very different processing methods can be utilized to rapidly examine the structures and dynamics in highly-driven systems over large composition ranges.
