Solute-defect Interaction in the Framework of a Defactant Concept

TL;DR: In this article, the defect formation energies of defects are quantitatively described in the defactant concept, which is defined as an excess of a different substance at boundaries, leading to a reduced driving force for their annihilation.

Positron annihilation spectroscopy of defects in nuclear and irradiated materials- a review

TL;DR: Positron annihilation spectroscopy (PAS) is the only probe that can detect individual atomic vacancies and small and large vacancy clusters induced by irradiation with remarkable sensitivity, providing information about their size, concentration, and chemical environment as discussed by the authors.
Journal ArticleDOI

A review of fatigue damage detection and measurement techniques

TL;DR: The reliability, advantages, weaknesses, case/material dependency and applicability of each method are compared and tabulated for making a framework for choosing a suitable technique for fatigue crack or damage detection of material or components.

Efficient iterative schemes for ab initio total-energy calculations using a plane-wave basis set.

TL;DR: An efficient scheme for calculating the Kohn-Sham ground state of metallic systems using pseudopotentials and a plane-wave basis set is presented and the application of Pulay's DIIS method to the iterative diagonalization of large matrices will be discussed.

Projector augmented-wave method

TL;DR: An approach for electronic structure calculations is described that generalizes both the pseudopotential method and the linear augmented-plane-wave (LAPW) method in a natural way and can be used to treat first-row and transition-metal elements with affordable effort and provides access to the full wave function.

From ultrasoft pseudopotentials to the projector augmented-wave method

TL;DR: In this paper, the formal relationship between US Vanderbilt-type pseudopotentials and Blochl's projector augmented wave (PAW) method is derived and the Hamilton operator, the forces, and the stress tensor are derived for this modified PAW functional.
