In the present endeavor, a Gleeble thermo-mechanical simulator has been used to simulate
subzones of the heat-affected zone (HAZ) of boron-free P91 and boron-modified P91B …

In the present study, welding of P92 steel and 304H austenitic stainless steel (304H ASS)
plates (thickness: 8 mm) was performed using activated flux-gas tungsten arc welding …

EPRI‐supported research has identified critical material information regarding the factors
affecting the performance of creep strength‐enhanced ferritic steels, in general, and Grade …

Creep fracture behaviour of tempered martensitic steels is generally governed by the
process of cavity nucleation, growth and coalescence into microcracks. Therefore, creep …

This paper reports the short-term creep behaviour at elevated temperatures of a MarBN steel
variant. Creep tests were performed at three different temperatures (625° C, 650° C and …

An excessive concentration of boron in the 9% Cr tempered martensitic steels alloyed with
nitrogen has a detrimental effect on creep performance, as relatively large boron nitride …

Martensitic steels strengthened by Boron and Nitrogen additions (MarBN) were developed
for high temperature/high stress service in power plant for periods of many years and are …

The evolution of grain size and structure morphology across the CrMoV welded joint were
investigated. The tensile properties of subzones in the weldment were measured by …

The weldments made from the 9–12% Cr tempered martensitic steel are associated with a
complex microstructure arising from complicated thermal histories of the fusion and heat …

Welding of shipbuilding steels is considered a challenge. First, because of the requirement
to keep the metallurgical continuity that gives the material mechanical strength and …
