Dissimilar metal joints between ferritic and austenitic alloys are susceptible to premature
failure due to diffusive carbon loss from the ferritic alloy driven by abrupt changes in carbon …

In the postweld heat-treated (PWHT) fusion welded modified 9Cr-1Mo steel joint, a soft zone
was identified at the outer edge of the heat-affected zone (HAZ) of the base metal adjacent …

Constitutive equations have been developed to describe the creep behaviour of a 0.5 Cr-0.5
Mo-0.25 V ferritic steel under uniaxial and multi-axial states of stress, as well as over the …

The circumferential butt-welded pipe was fabricated using 2.25 Cr-1Mo steel and then
subjected to local post-weld heat treatment (LPWHT) for releasing residual stress after multi …

Evaluations of creep rupture properties of dissimilar weld joints of 2.25 Cr-1Mo, 9Cr-1Mo,
and 9Cr-1MoVNb steels with Alloy 800 at 823 K were carried out. The joints were fabricated …

A major high temperature failure mechanism for weldments in ferritic steel steam pipework is
circumferential creep cracking within the region of the heat affected zone, adjacent to the …

Fast breeder reactors (FBRs) are destined to play a crucial role in the Indian nuclear power
programme in the foreseeable future. FBR technology involves a multi-disciplinary approach …

In this paper, the effects of high temperature deformation on the microstructure, mechanical
properties and hydrogen embrittlement (HE) of the 2.25 Cr–1Mo-0.25 V steel was …

Recent research activities on high temperature behaviour of welded structures are briefly
reviewed in this paper. A local deformation measuring technique is developed to determine …

The influence of tempering treatments on toughness and austenite stability was conducted
on modified 9Cr–1Mo welds. Deteriorated impact toughness was noticed for the welds …
