Journal ArticleDOI
Characterization of Microstructures across the Heat-Affected Zone of the Modified 9Cr-1Mo Weld Joint to Understand Its Role in Promoting Type IV Cracking
TL;DR: In this paper, a soft zone was identified at the outer edge of the heat-affected zone (HAZ) of the base metal adjacent to the deposited weld metal, leading to premature failure of the weld joint in the intercritical region of the HAZ, commonly known as type IV cracking.
Journal ArticleDOI
Comparison of creep rupture behaviour of type 316L(N) austenitic stainless steel joints welded by TIG and activated TIG welding processes
T. Sakthivel,Madavan Vasudevan,K. Laha,P. Parameswaran,K.S. Chandravathi,M.D. Mathew,A.K. Bhaduri +6 more
TL;DR: In this paper, the weld joints of single-pass activated TIG (A-TIG) and multi-pass conventional TIG welding processes were studied at 923 K over a stress range of 160-280 MPa.
Journal ArticleDOI
Creep rupture behavior of 9Cr–1.8W–0.5Mo–VNb (ASME grade 92) ferritic steel weld joint
T. Sakthivel,Madavan Vasudevan,K. Laha,P. Parameswaran,K.S. Chandravathi,S. Panneer Selvi,V. Maduraimuthu,M.D. Mathew +7 more
TL;DR: In this article, a steel weld joint fabricated by activated TIG (A-TIG) welding process has been investigated at 923 K over a stress range of 80-150 MPa.
Journal ArticleDOI
An assessment of creep deformation and fracture behavior of 2.25Cr-1Mo similar and dissimilar weld joints
TL;DR: In this article, the deformation and fracture behavior of a 2.25Cr-1Mo steel base metal, and a dissimilar weld joint at 823 K over a stress range of 90 to 250 MPa has been carried out.
Journal ArticleDOI
Microstructure and tensile properties of modified 9Cr–1Mo steel (grade 91)
TL;DR: In this paper, the influence of different soaking temperatures in the range 973 −1623 K (below Ac 1 to above Ac 4) before oil quenching and tempering, on the microstructure, hardness, grain size, and tensile properties of modified 9Cr −1Mo steel has been studied.
