TL;DR: In this article, the authors reviewed various theories of dislocation creep, with particular emphasis on the contribution of precipitates to the "friction stress" resisting dislocation motion, and developed a model which considers the contribution to the friction stress of the back stress resulting from the climb process.

TL;DR: In this article, the authors established the precipitation processes which occur on ageing metastable β phase specimens above the monotectoid temperature (T mono ) by using optical and electron microscopy together with electron and X-ray diffraction.

TL;DR: In this article, a reproducible distribution of creep cavities on the grain boundaries was achieved by retaining specimens at a constant creep strain ( ϵ = 0.13) and sintering heat treatments to remove these cavities were carried out at temperatures in the range 873-1073 K under superimposed hydrostatic pressures of argon gas up to 62 MNm −2.

TL;DR: In this paper, the influence of temper embrittling heat treatment on the intergranular stress corrosion susceptibility of an Fe-3 wt.% Ni alloy containing minor additions of tin or phosphorus has been investigated.

TL;DR: In this paper, a controlled addition of the impurity element phosphorus has been made to a base melt of 2 1 4% Cr 1%Mo steel, heat treated to produce microstructures typical of those encountered in both service components and the heat affected zones of weldments.
