Corrosion of the heat‐affected zone of stainless steel weldments
Anti-Corrosion Methods and Materials, 2010PurposeThe purpose of this paper is to investigate the corrosion of the heat‐affected zone (HAZ) and weld zone of austenitic stainless steels that have been welded using two different processes. The corrosion behavior is evaluated in synthetic seawater using the electrochemical polarization technique.Design/methodology/approachWelded and unwelded UNS ...

Heat-Affected Zone as Critical Location in Pressure Equipment
2016The majority of pressure equipment is made from joining by welding parts or sub-assemblies. Welded structure should be produced by spending minimum of cost, assuring in the same time required function and safety. By proper selection of welded joint and material, designer determines the properties of final product, and also possibility of its ...

Prediction of heat-affected zone using Grey theory
Journal of Materials Processing Technology, 2002Abstract The amount of deformation and the residual stress, which influence welded plates, are related directly to three aspects of the welding process: the method of heat input; the welding speed and the geometrical conditions; limitations of the weldment.

Structure of the heat-affected zone in weldments of steel 24Kh2NMFA
Metal Science and Heat Treatment, 19771. With multipass welding of rotor steel 24Kh2NMFA granular bainite is formed in the HAZ. The matrix of the bainite is the α solid solution formed by martensitic kinetics; small areas of granular or elongated form evenly distributed in the matrix consist of martensite and retained austenite. 2.

Prediction of hardness distribution in steel heat affected zone
Science and Technology of Welding and Joining, 1999A practical method to predict the heat affected zone (HAZ) hardness distribution was studied by considering the effects of prior austenite grain size and tempering on hardenability. For conventionally rolled and thermomechanically processed steels (400–490 MPa grade steels), the hardness distribution between the fusion and Ac3 lines can be fairly well

Microfissuring of Alloy 718 in the Weld Heat-Affected Zone
JOM, 1988Alloy 718 suffers from microfissuring in the weld heat-affected zone, and compositional, structural and mechanistic causes of this defect have been examined. Both bulk sulfur and bulk carbon increase microfissuring, and heat treatments typical ofhomogenization, solution annealing and age hardening reveal that microfissuring is sensitive to the ...

PWSCC Susceptibility in Heat Affected Zones of Alloy 600
2011The recent field experience and several experimental results have shown the possible deleterious effect of a heat affected zone (HAZ) induced by welding on the susceptibility to the stress corrosion cracking (SCC) of Alloy 600 of bottom penetrations exposed to primary water of PWRs.
