Diagram for the prediction of weld heat-affected zone microstructure
Metals Technology, 1977Abstract The performance of welded joints, both during fabrication and operation, can depend critically upon the microstructure ofthe heat-affected zone, which, in a steel of given composition, is a function of the welding procedure andjoint geometry. The selection of suitable welding conditions which avoid the formation of crack-sensitive structures ...

Grain refinement in coarse-grained heat-affected zone of Al–Ti–Mg complex deoxidised steel
, 2019The particles and microstructure characteristics of coarse-grained heat-affected zone (CGHAZ) in Al–Ti–Mg killed steels with different Al contents were investigated. The results show that inclusion in high Al steel consists of Al–Mg oxide surrounded with

Hardness Profiles of Quenched Steel Heat Affected Zones
Materials Science Forum, 2013This paper reports the effects of chemical composition on the hardness of the heat affected zone of re-austenitized and water quenched steels. Heat affected zone peak temperatures in the range 300–1350 °C were simulated using a Gleeble 3800 simulator using thermal cycles appropriate to welds with cooling times between 800 and 500 °C of 12s. The maximum

Heat-Affected Zone Hardness Limits for In-Service Welding
2008 7th International Pipeline Conference, Volume 3, 2008Welds made onto in-service pipelines are particularly susceptible to hydrogen cracking. During qualification of welding procedures, limits are often imposed on heat-affected zone hardness (e.g., 350 HV max.) as a way to avoid cracking. The hardness level below which hydrogen cracking does not occur is not a fixed value, but varies as a function of ...

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.
