TL;DR: This study focuses on identifying a correlation between the mean secondary and tertiary γ′ size and the cooling rate from solution treatment temperature, and derives a derived model that captures the correlation correctly despite its simplicity, and is able to predict the mean primary and secondary precipitate size in a nickel superalloy, without complex modeling.

TL;DR: In this paper, the effect of surface damage in the fatigue life of nickel superalloys is evaluated using a finite element (FE) model, and the residual stress distribution obtained via the FE model was subsequently used in a fatigue short crack growth model for an estimation of the fatigue lifetime of dented specimens.

TL;DR: In this paper, the residual stress field and the underlying microstructural features arising in friction stir welding (FSW) butt joints and their effect on the fatigue performance of this type of weldments were evaluated by means of modern experimental techniques.

TL;DR: In this article, the authors review a wide range of recent experimental studies using the Engin-X materials engineering instrument at the ISIS neutron source and show how the technique provides the basis for developing improved insight into materials of great importance to applications and industry.

TL;DR: The development of high-energy transmission Laue (HETL) micro- beam X-ray diffraction is described, extending the micro-beam Laue technique to significantly higher photon energies (50-150 keV), which allows the probing of thicker sample sections, with the potential for grain-level characterization of real engineering components.
