Relationship between microstructure and mechanical behaviour of thermomechanically optimised 9-12% Cr steels [PDF]
, 2010 International audienceThe development of Generation IV fission nuclear reactors and fusion nuclear reactorsrequires materials able to resist to high temperature (650°C) creep, but also to creep-fatigue.Martensitic 9-12%Cr steels are candidate materials ...

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 9, Page 1275-1293, 1 May 2024.Abstract This paper presents a novel computer‐aided computational framework to determine the optimum shape parameters in a welding heat source model using a coupled supervised Gaussian process regression (GPR) and genetic algorithm (GA) approach in estimating the welding residual stresses. The experimental X‐ray diffraction (XRD) approach validates the

Alleviating Neonatal Intensive Care Unit Stress: A Chinese Medicine Approach in Neonatal Rats
BioMed Research International, Volume 2024, Issue 1, 2024.Background. Premature infants are exposed to numerous stressors in neonatal intensive care unit (NICU) during a crucial period for brain development; this period exerts long‐term influences on cognitive and behavioral development. Aims. To evaluate the effect of NICU‐related stress on neonatal rat pups and explore the effect of Chinese medicine ...

Creep deformation behavior and residual life prediction of low hardness P91 steel welded joints
Journal of Materials Research and TechnologyThe remaining creep life of the reheat section pipeline of low hardness P91 steel replaced in a certain power plant was studied. The rupture behavior of the joint was studied using metallographic microscope (OM), scanning electron microscope (SEM), and ...
