The conventional trial and error approach for exploring glass formation in multicomponent alloy systems is a time-consuming endeavor and provides little insight into critical cooling rates and thermal stability. In this work, multiple alloy systems were explored using laser-deposition fabrication that enables the evaluation of a large continuous composition range in a single fabrication step. Topographically-smooth surface regions were rapidly identified using optical microscopy, and then confirmed to be amorphous via TEM. By varying laser processing parameters, the optimum glass-forming compositions within a fabricated library could be experimentally deduced. Furthermore, nanoindentation was used as a high-throughput characterization tool to establish compositional trends of indentation hardness and modulus within a large region of composition space. These trends in turn may provide valuable insight for designing good glass formers with improved plasticity.
