The paper presents first of its kind study on the creep-fatigue interaction (CFI) behavior of
simulated coarse grain (CG), fine grain (FG) and inter-critical (IC) heat-affected zones …

A methodology is presented for physically-based prediction of high temperature fatigue
crack initiation in 9Cr steels, with a focus on material inhomogeneity due to welding-induced …

Low cycle fatigue tests were conducted on the weld metal, coarse grain heat-affected zone
(CGHAZ), fine grain heat-affected zone (FGHAZ), inter-critical heat-affected zone (ICHAZ) …

In this study, the microstructures of the three principal heat-affected zones (HAZs) of the P91
steel weld joint were simulated using appropriate heat treatments at different soaking …

Components subjected to operation at a temperature in the range of 0.4 Tm (Melting
temperature of component) and above are prone to failure due to creep. The failure …

Wire-arc additive manufacturing (WAAM) is a promising technique to fabricate large-size
components with high efficiency. However, the changes in microstructure induced by WAAM …

The low cycle fatigue (LCF) behavior of P91 steel weld joint (WJ), prepared by gas tungsten
arc welding, has been investigated both experimentally and numerically. However, due to …

The geometrical increase in the demand for electrical energy has posed serious pressure on
the power generation components such as the steam pipes due to the consequential …

The influence of heterogeneous welding microstructure on the stress relaxation cracking
(SRC) in the SRC-resistant 316L (N) steel was investigated. To trigger SRC, pre-straining by …

Tensile deformation behavior of the heat affected zone (HAZ) of Mod. 9Cr-1Mo weldment
has been characterized. Different microstructural regions (coarse grain, fine grain and inter …
