The stability of precipitates in an irradiation environment

Low-temperature iron-nitride phase transformations induced by ion bombardment

“…9 As a consequence he arrives at the conclusion that the equilibrium configuration of the solid under irradiation with flux and temperature T is identical to the configuration at ϭ0 and TЈϭT͑1ϩ⌬͒, where ⌬ has a simple expression in terms of the irradiation parameters and characteristic of the material. 12 In principle our results can be explained, at least qualitatively, by both models.…”

“…In recent years extensive work has been done on the stability of coherent and semicoherent precipitates under heavy ion and neutron irradiations; [9][10][11][12] however, the result of these studies has not lead to a conclusive model. Nelson and co-workers 9 have argued that when metals or alloys containing precipitates are irradiated, the thermodynamic equilibrium can be changed by two processes: first, dissolution of the precipitates through cascade dissolution and/or disordering effects, and second, radiation-enhanced diffusion of the solute within the host matrix.…”

Atomic-scale design of radiation-tolerant nanocomposites

“…An alternative route to the synthesis of radiation-resistant nanostructures is offered by taking advantage of irradiation-induced self-organization reactions at the nanoscale. Examples of these self-organization reactions triggered by irradiation are (i) the stabilization of ordered gamma prime precipitates a few nanometers in diameter in a gamma matrix in Ni-Al alloys [37]; (ii) the formation of void and bubbles lattices in many metals and alloys (see [38] for a review); and (iii) the patterning of nanoscale phases in immiscible alloy systems [39][40][41][42][43], for instance in Cu-Ag, Cu-Fe, Cu-Co, Cu-Nb, Cu-Mo, and Cu-W.…”

Void-Precipitate Association During Neutron Irradiation of Austenitic Stainless Steel

“…From about [1964][1965][1966][1967][1968][1969][1970][1971][1972], precipitation in neutron irradiated steels was primarily thought to be an irradiation enhanced thermal phenomenon [14][15][16]. From 1972From -1978, the discovery of many irradiation induced [9,17,13] and/or nickel and silicon rich phases [19,20], suggested that precipitation under irradiation may be quite different from that occurring under thermal aging.…”
