Heat Affected Zone Softening Susceptibility Test

Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2020
Abstract 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, 1986
Abstract 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, 1994
Summary 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 ...
