Journal ArticleDOI
Modeling the strengthening response to aging process of heat-treatable aluminum alloys containing plate/disc- or rod/needle-shaped precipitates
TL;DR: In this paper, a previous model was modified to present quantitative relationships between the yield strengths of the alloys and the sizes, volume percentages of precipitates, related to aging temperature and aging time as well as alloy compositions, while the strengthening of the precipitates was coupled with the whole evolution process.
Journal ArticleDOI
Role of interfaces in kinetics of internal shape changes
TL;DR: In this paper, the role of interfacial properties, notably interfacial energy σ and mobility μ, in a series of solid-state reactions that involve the change of size and shape of second-phase precipitates is discussed.
Journal ArticleDOI
Influence of interfacial properties on the kinetics of precipitation and precipitate coarsening in aluminium-silver alloys
Maurizio Ferrante,R.D. Doherty +1 more
TL;DR: In this paper, the lengths and thickness of hexagonal Ag2Al precipitates were studied under two conditions; first, during free precipitate growth in supersaturated solid solutions before soft impingement and secondly during Ostwald Ripening.
Journal ArticleDOI
Kinetics of growth and coarsening of faceted hexagonal precipitates in an f.c.c. matrix—I. Experimental observations
K.E. Rajab,Roger D. Doherty +1 more
TL;DR: In this article, the authors reported on the precipitation kinetics of a range of Al-Ag alloys under different conditions of aging temperature and supersaturation, and the interpretation of the results is that at the start of the reaction thickening is inhibited due to a low density of growth ledges.

Journal ArticleDOI
Theory of Growth of Spherical Precipitates from Solid Solution
TL;DR: In this paper, the radius of a spherical precipitate particle growing in a solid solution of initially uniform composition was shown to be equal to α(Dt)½, where D is the atomic diffusion coefficient, t the time of growth, and α, the growth coefficient, is a dimensionless function of the pertinent compositions.
Journal ArticleDOI
The coarsening behaviour of θ″ and θ′ precipitates in two Al-Cu alloys
J.D. Boyd,R.B. Nicholson +1 more
TL;DR: In this article, the coarsening kinetics of disc-shaped particles were investigated using the Lifshitz-Wagner theory, modified for the case of discshaped particles.
Journal ArticleDOI
The growth of γ plates in an Al-15% Ag alloy
C Laird,H.I Aaronson +1 more
TL;DR: In this paper, the mechanisms and kinetics of plate-shaped precipitate morphologies have been studied in h.c.p. γ plates grown in an Al-15% Ag alloy.
Journal ArticleDOI
Kinetics of growth of platelike precipitates
R Sankaran,Campbell Laird +1 more
TL;DR: In this paper, the authors investigated the role of the broad face coherency strain field which accelerates the lengthening and thickening of plate-like precipitates and found that the length of coherent plates is much greater than those of the same kinds of plates when semicoherent.
Journal ArticleDOI
A calorimetric determination of precipitate interfacial energies in two AlCu alloys
J.D. Boyd,R.B. Nicholson +1 more
TL;DR: In this article, an isothermal calorimeter has been used to determine the heat evolution during coarsening of the θ and θ′ precipitates in an Al-4% Cu and an Al 4% Cu-0.1% Cd alloy.
