An assessment of high voltage electron microscopy (HVEM). An invited review
M.H. Loretto,R.E. Smallman +1 more
TL;DR: High voltage electron microscopy (HVEM) has been extensively applied in the field of materials science as discussed by the authors, covering the study of heavy metals, ceramics and minerals, large-scale structures, dynamic processes and radiation damage.
Journal ArticleDOI
Dynamic failure of solids
TL;DR: In this article, the authors present a methodology that relates the kinetics of material failure on the microstructural level to continuum mechanics, by introducing micro-structural descriptions of damage into the continuum constitutive relations as internal state variables.

Creep cavitation in metals
Michael E. Kassner,T.A. Hayes +1 more
TL;DR: A review of the state-of-the-art of the understanding of cavity formation during stages I and II (primary and secondary) creep in polycrystalline metals and alloys, particularly at elevated temperatures, can be found in this article.
Journal ArticleDOI
Nucleation of cavities at second phase particles in grain boundaries
TL;DR: In this paper, a kinetic approach is used to explain the nucleation of cavities in grain boundaries at elevated temperature, under the influence of a tensile stress, vacancies cluster together and form cavities.

Creep cavitation in 304 stainless steel
I-Wei Chen,A.S. Argon +1 more
TL;DR: In this article, two specially developed techniques were used to study the nucleation and growth of grain-boundary cavities in 304 stainless steel at 0.5 Tm and found that cavities nucleated heterogeneously throughout the creep history and those observed were well in their growth stage.

Growth of voids in metals during diffusion and creep
R.W Balluffi,L.L Seigle +1 more
TL;DR: In this paper, a study of the thermodynamic conditions under which voids may grow from suitable nuclei in a metal by a mechanism of vacancy aggregation under the influence of stress and vacancy supersaturation is made.

Grain boundary dislocations in aluminium bicrystals after high-temperature deformation
TL;DR: In this paper, the authors examined aluminum bicrystals containing a symmetrical tilt grain boundary with thin-foil electron microscopy after high-temperature shear deformation.

The entropy associated with the magnetic transitions of the HCP rare earth metals
TL;DR: In this paper, the heat capacity results of the twelve metals listed in Table I can be represented by the above equations to within 0.i0 cal/deg (g atom) between 20°K and 50°K.

The effect of room temperature pre‐strain on grain boundary cavitation in Nimonic 8oA
B. F. Dyson,D. E. Henn +1 more
TL;DR: In this paper, the cavities all lay on grain boundaries but were inhomogeneously distributed; a grain boundary usually contained either many cavities or none at all, and it was concluded that the cavitation is a direct result of decohesion at the grain boundaries during the pre-straining and not due to any creep process.
