This study explores the benefits of utilizing recently developed protocols for microstructure quantification and the multiresolution mechanical characterization of Ti-based bulk metallic glass matrix composites. Four alloys with different compositions and amorphous (glass) fractions were studied. Microstructure quantification of the amorphous and crystalline phase in these alloys was performed using rotationally invariant 2-point spatial statistics and principal component analysis on approximately 1300 micrographs. Mechanical properties of the constituent phases as well as the bulk mechanical properties of the composites were measured using recently established high-throughput multiresolution spherical indentation stress–strain protocols. The results showed that decreasing amorphous volume fraction results in a decrease in both bulk Young’s modulus and the bulk yield strength of the samples, without significant changes in the mechanical properties of the constituent phases.
