Boron addition to AISI A213/P91 steel: Preliminary investigation on microstructural evolution and microhardness at simulated heat‐affected zone

Materialwissenschaft und Werkstofftechnik, 2022
The motivation behind present investigation has been a step to create preliminary understanding towards structure‐property correlation i. e., microstructure and microhardness in presence of boron in P91 steel and in its subzones of heat‐affected zone ...

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 ...
