Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Mechanism Verification of Electrochemical Migration of Fine Cu Wiring

Japanese Journal of Applied Physics, 2011
The mechanisms of electrochemical migration and consequent insulation failure in fine-pitch Cu wiring (line/space = 3 µm/3 µm) are investigated. A model in which the migration takes place in the presence of water in a phenol-based resin–resin interface between biased Cu traces is proposed. Replacing the bottom resin layer by a SiN layer is found to

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
