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 ...

Dormant Comets Among the Near-Earth Object Population: A Meteor-Based Survey

, 2016
Dormant comets in the near-Earth object (NEO) population are thought to be involved in the terrestrial accretion of water and organic materials. Identification of dormant comets is difficult as they are observationally indistinguishable from their ...

Estimating the Influences of Prior Residual Stress on the Creep Rupture Mechanism for P92 Steel

Metals, 2019
Creep damage is one of the main failure mechanisms of high Cr heat-resistant steel in power plants. Due to the complex changes of stress, strain, and damage at the tip of a creep crack with time, it is difficult to accurately evaluate the effects of ...

Creep-Fatigue Crack Growth in Power Plant Components [PDF]

, 2017
In components operating at high temperature, the presence of defect, that may derive from manufacturing process or operating under critical conditions, could raise to creep-fatigue crack growth even at low loading conditions.
