A toughness study of the weld heat-affected zone of a 9Cr–1Mo steel

Microstructural Study of Welded Joints in a High Temperature Martensitic-ferritic ASTM A335 P91 Steel

“…In these last regions, microscopic observations suggest that precipitates h g f e have coarsened and lowered their number density with respect to transformed regions. The same observation has already been reported in the previous literature (Moitra et al (2002)). …”

The Influence of Thermal Exposure and Hydrogen Charging on the Notch Tensile Properties and Fracture Behaviour of Dissimilar T91/TP316H Weldments

“…Heat-affected zones (HAZ) represent potentially weak localities of weldments because of their microstructural degradation induced by welding thermal cycle, manifested in general by coarsening of prior austenitic grains and secondary phase particles compared to unaffected base materials [5]. Inner parts of power plant boiler tubing and/or piping may operate in hydrogen containing environments since the used work media, i.e.…”

Charpy energy–lateral expansion relations for a wide range of steels

“…The steels covered are: AISI 316 SSs in the solution treated (base metal-BM) and various thermal-aged/cold-worked (CW) conditions (including some old unpublished data) [4][5][6][7], AISI 308 SS weld [8,6], CF3 castings [7], AISI 403 SS [9], ASTM A533B type steels [10], 9Cr-1Mo steels [11] and welds [12] and their simulated heat-affected zones (HAZ) [13,14] and a service-exposed 2.25Cr-1Mo steel [15]. The material designations used for AISI 316 SS are solution-treated (ST-TS or BM: 1323 K/0.5 h plus water quench), STC1073 K/ 50 h aged (H5), STC1073 K/1008 h aged (H8), STC20% cold-work (CW) and CWCdouble aged conditions (GT).…”
