Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Calculation Method for the Heat Affected Zone of Coiled Tubing Circumferential Welding

Shiyou jixie, 2019
Coiled tubing circumferential welding is indispensable in the manufacturing and on-site repair process. The heat-affected zone caused by welding not only directly reduces the overall strength of the coiled tubing, but also makes the coiled tubing more ...

Study on ductile fracture of electroslag welding and its heat affected zones

Hanjie xuebao
Electroslag 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.
