Synchrotron X-ray-informed machine learning for local hardness mapping in a Cu–Ni–Ti–Hf–Zr high-entropy shape-memory alloy

A supervised machine-learning framework was used to relate colocated synchrotron X-ray fluorescence (XRF), X-ray nanodiffraction (XND), thermodynamic descriptors, and nanoindentation measurements to local hardness in an as-cast Cu 15 Ni 35 Ti 25 Hf 12. 5Zr 12.5 high-entropy shape...

Effect of Indium and Nickel on Impact Toughness of Sn–0.7Cu Solder: Interplay of Solubility, Phase Configuration, and an Improved Ductile‐to‐Brittle Transition Temperature Analysis

Reliability of solder joints under sudden mechanical shocks at cryogenic conditions is critical for deep‐space electronics, where launch‐induced vibrations, pyrotechnic‐shock, micro‐meteoroid impacts, or thermally induced stress transients can compromise structural interconnect i...
