Role of butter layer in low-cycle fatigue behavior of modified 9Cr and CrMoV dissimilar rotor welded joint
TL;DR: In this paper, the role of butter layer (BL) in low-cycle fatigue (LCF) behavior of modified 9Cr steel and CrMoV steel dissimilar welded joint was investigated.

Soft zone formation by carbon migration and its effect on the high-cycle fatigue in 9% Cr–CrMoV dissimilar welded joint
TL;DR: In this paper, carbon migration in the welds between 9% Cr steel and CrMoV steel during high-cycle fatigue (HCF) test at various temperatures was studied.

Microstructure characteristics and temperature-dependent high cycle fatigue behavior of advanced 9% Cr/CrMoV dissimilarly welded joint
TL;DR: In this paper, the authors studied the high-cycle fatigue (HCF) behavior of an advanced 9% Cr/CrMoV dissimilarly welded joint at different temperatures and found that the failure occurred at the side of CrMoV base metal (BM), weld metal (WM) and heat affected zone (HAZ) of the side over 5×107 cycles for the specimens tested at RT, 400°C and 470°C.

Microstructural characterization and wide temperature range mechanical properties of NiCrMoV steel welded joint with heavy section
TL;DR: In this paper, the mechanical properties including the tensile and impact toughness of the welded joints (WJs) with a wide temperature range were systematically investigated, which indicated that the high-temperature tempered martensite and tempered bainite, as the main microstructure in WJ, were responsible for the improved comprehensive mechanical properties of the WJ.
