Abstract Scope |
Following multiple studies of high-rate deformation in pure Cu, here we investigate the effect of particle size and volume fraction on spall strength and hardness in Cu using Cu-Ti alloys as model materials and robotically controlled characterization methods. We synthesized the Cu-Ti alloys in a combinatorial manner by sputter depositing 200 microns thick, free-standing foils with compositions varying from Cu-1at% Ti to Cu-10at% Ti. We describe homogenization above solvus temperatures and subsequent aging to obtain a wide variation in Cu4Ti precipitate volume fraction and size. 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 and to identify the underlying deformation mechanisms. |
