Study on ductile fracture of electroslag welding and its heat affected zones
Hanjie xuebaoElectroslag welding involves high heat input, which may cause material hardening in the weld and heat-affected zone. At the same time, the electroslag weld is in an inaccessible state, making the welding quality difficult to control.

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
