Impact of creep-fatigue interaction on divertor tungsten under high heat flux

Nuclear Materials and Energy, 2023
High heat flux as 20 MW m−2 during stationary operation can be foreseen in future fusion devices, leading to recrystallization and thermal creep in tungsten targets. Both recrystallization and thermal creep impact would play significant roles in service.

Creep-Rupture Strength of Precracked Specimens

Journal of the Society of Materials Science, Japan, 1971
The creep-rupture strength of precracked specimens made of S10C carbon steel was investigated at 450°C as an extreme case of the strength of specimens with a sharp notch. Two methods were employed for making precracks. One was by using a rotating bending fatigue testing machine with specimens having a sharp notch, as had often been used by many ...

Effect of Cold Work on Creep Rupture Strength of Alloy263 [PDF]

International Journal of Materials Science and Applications, 2017
Creep rupture strength and the microstructure change during creep deformation of pre-strained Alloy263 were investigated. Creep rupture tests were conducted at 1023, 1073 K at stress range from 120 to 250 MPa. Creep strength of the pre-strained samples was higher than that of the non-strained samples. However, rupture strain of the pre-strained samples
