Heat Affected Zone Softening Susceptibility Test
Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2020Abstract There have been a number of unexpected girth weld failures in pipelines, both in-service and during pre-service hydrostatic testing. Investigation of these incidents indicated that the line pipe met industry standard requirements, such as API 5L and the welding procedures had been qualified to API 1104 and construction welding ...

Heat affected zone COD testing
Theoretical and Applied Fracture Mechanics, 1986Abstract The paper focusses on additional COD test validity criteria which are seen as necessary to ensure the accurate assessment of heat affected zone toughness. Theoretical considerations indicate that it is necessary for the COD notch to intersect the heat affected zone for at least 8% of the specimen thickness in order to ensure accurate ...

Heat-Affected Zones in Grinding Steel
CIRP Annals, 1994Summary Two well known forms of metallurgical damage of ground surfaces involve untempered and overtempered martensite. Both of these forms of metallurgical damage involve martensitic transformations. This paper reviews the nature of such transformations and the special characteristics that pertain in grinding where the time at temperature before ...

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

Simulated Heat-Affected Zone of Steel 4330V
Materials Performance and Characterization, 2019Abstract Steel 4330V is a material that contains an addition of vanadium (approximately 0.06 wt. %). The steel is widely used in the mining and petroleum industries. The steel microstructure contains tempered martensite. The high carbon equivalent of the steel makes it difficult to weld.
