Formation of Lamellar Carbides in Alloy 617-HAZ and Their Role in the Impact Toughness of Alloy 617/9%Cr Dissimilar Welded Joint
TL;DR: In this article, the relationship between the microstructure and impact toughness, especially the formation of the lamellar carbides and its effect on the impact toughness of the heat-affected zone of Alloy 617 (Alloy 617-HAZ), was systematically investigated.

Failure Transition Mechanism of Stress Rupture Performance of the Inconel 625/9 Pct Cr Steel Dissimilar Welded Joint
TL;DR: In this paper, the relationship between the stress and rupture time was obtained to evaluate the long-term performance of the welded joint (WJ), based on a series of stress rupture tests at 620-°C under 110 to 170-MPa and at 650-°c under 80 to 110 -MPa.

Prevention of carbon migration in 9% Cr/CrMoV dissimilar welded joint by adding tungsten inert gas overlaying layer
TL;DR: In this article, two welding techniques were used to fabricate 9% chromium and CrMoV dissimilar welded joint, and the results showed that the carbon migration only appeared in the specimen using narrow gap submerged arc welding (NG-SAW) technique, yet it can be effectively prevented by adding tungsten inert gas (TIG) overlaying process before the NG- SAW.

Anomalous residual austenite formation in root of welding layers of 9% Cr/CrMoV dissimilar welded joint
TL;DR: The morphology and distribution of residual austenite in the welded zone of 9% Cr/CrMoV dissimilar welded joint were observed by color metallographic method as mentioned in this paper.

Clarification of the false liquation crack existed in 9% Cr/CrMoV dissimilar welded joint by comparative etching process and in situ laser scanning confocal microscope
TL;DR: In this paper, a comparative etching was employed to reveal the effect of various etching processes on the determination of liquation cracks, and the formation process and mechanism of the false liquation crack in 9% Cr/CrMoV welded joint were clarified.
