In present research article, microstructure evolution in P91 steel and their weldments are
reviewed in as-virgin and heat treatment and creep exposure condition. The thermal stability …

This review summarizes the strengthening mechanisms of reduced activation
ferritic/martensitic (RAFM) steels. High-angle grain boundaries, subgrain boundaries, nano …

This study focuses on the development and characterization of a novel high Mo-element
maraging steel fabricated using laser additive manufacturing. The maraging steel was …

A dissimilar laser beam welded joint of ferritic/martensitic P92 steel, and 304L austenitic
stainless steel (ASS) has been examined in as-weld and post-weld heat treatment (PWHT) …

FeCoCrNiMn based high entropy alloys (HEAs) doped with different carbon contents were
prepared by vacuum arc melting. The effects of carbon on phase composition and …

Cr-Mo creep strength enhanced ferritic (CSEF) steels are mainly used in nuclear reactors
and ultra-supercritical (USC) power plants for superheater tubes and header. The present …

In this analysis, friction stir processing (FSP) was applied to the Si rich TIG welded joint to
study the influence of multi-pass FSP (MPFSP) on microstructure, hardness and tensile …

Restrictive operating conditions (even exceeding 700° C) of materials in advanced ultra
super critical (AUSC) power plants and the need to minimize manufacturing and …

This article deals with the dissimilar joining of two different grade Cr-Mo steel (2.25 Cr-1Mo:
P22 and modified 9Cr-1Mo: P91) for power plant application. The dissimilar butt-welded …

Wire-arc additive manufacturing (WAAM) of Grade 91 steel (P91) is demonstrated for the first
time. This alloy has been widely used in pressure vessel components of thermal and nuclear …
