Weld consumables and PWHT for P92 power plant steel [PDF]

, 2013
P92 steel is a high-alloy steel that has been specifically designed for operating at high temperatures (600°C - 650°C) and has found wide use in the power generation industry, particularly since 2005. For the successful installation and use of this advanced steel, all aspects of its behaviour, in terms of both metallurgy and in-service behaviour, must ...

Achievement of superior strength in Al–Ni dissimilar joints through designing high-entropy alloy interlayer and post weld heat treatment

Journal of Materials Research and Technology
The formation of brittle intermetallic compounds (IMCs) at the interface during Al–Ni dissimilar joining deteriorates joint strength, thereby limiting their applicability in high-performance engineering structures.

Experimental study on local PWHT method by primary and secondary heating

Journal of Physics: Conference Series
Abstract Local PWHT is an important means to ensure the safety of tubular heat exchangers over their entire life cycle. This study presents a local PWHT method by primary and secondary heating and verifies the effectiveness of local PWHT for tubular heat exchangers. The results indicate that both the primary and secondary heating methods
