Microstructural Evolution and Mechanical Property Degradation of Sn0.5Ag0.7Cu5Bi Solder Joints with High Indium Alloying

Advanced Engineering Materials, EarlyView.
This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

Effect of Copper Content on the Microstructure and Mechanical Properties of As‐Cast Refractory MoNbTi Multiprincipal Element Alloys

Advanced Engineering Materials, EarlyView.
Copper addition profoundly impacts MoNbTi multiprincipal element alloys. This study reveals copper's dual role, promoting microstructural refinement and strengthening intermetallics at optimal concentrations. An ideal copper content significantly boosts hardness and compressive strength, achieving superior mechanical performance.

Design of Multiphase Compositionally Complex Alloys for Enhanced Hardness at Elevated Temperatures and Machinability: Comparative Study with Inconel 718

Advanced Engineering Materials, EarlyView.
This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance
