Abstract Scope |
In this study, we investigate the effect of grain size, particle size and volume fraction on spall strength and hardness in Cu and Cu-Ti alloys as model materials and robotically controlled characterization methods. We synthesized pure Cu and Cu-Ti alloys in a combinatorial manner by sputter depositing 200 mm thick, free-standing foils with compositions varying from Cu-1at% Ti to Cu-10at% Ti. We anneal pure Cu at different temperatures to vary the grain size and homogenize Cu-Ti alloys above solvus temperatures followed by subsequent aging to obtain a wide variation in Cu4Ti precipitates. Then we perform high-throughput characterization using a combination of tools such as transmission X-ray diffraction and laser shock to quantify microstructural parameters (precipitate size, structure, and volume fraction) and spall strength. Electron microscopy is also used to quantify grain size and precipitate morphology. |
