Interactions of grain boundaries with coherent precipitates during grain growth

TL;DR: In this article, electron micrographs have been used to establish the microstructural parameters characterising the γ′ dispersion and also the nature of the boundaryparticle interactions, which are interpreted in terms of models proposed by Zener and by Ashby and colleagues.
Journal ArticleDOI
Additive strengthening mechanisms in dispersion hardened polycrystals

TL;DR: In this paper, a linear combination of a matrix friction stress, an Orowan bowing stress, a matrix mean stress from the particles and a combined dislocation interaction term was derived by summing the dislocation density contributions from each of these three sources.
