07 Jun 1994TL;DR: In this paper, a well treating composition consisting of a gelled carrier, a particulate material, an epoxy resin system including at least one epoxy resins, and a finely-divided hardening agent is described.
Abstract: A well treating composition comprising: a gelled carrier; a particulate material; an epoxy resin system including at least one epoxy resin; and a finely-divided hardening agent which, when dissolved, is operable for hardening the epoxy resin. The finely-divided hardening agent is dispersed in the epoxy resin system. A method of treating a subterranean zone located in a well comprising the steps of: (a) preparing the above-described treating composition; (b) injecting the treating composition into the well such that the treating composition is placed in the subterranean zone; and (c) maintaining the finely-divided hardening agent under conditions such that, prior to injecting the treating composition into the well, the finely-divided hardening agent does not substantially dissolve.

TL;DR: In this article, the impact of irradiation on the microstructure and mechanical properties of nanostructured materials was investigated by electro deposition (ED) and severe plastic deformation (SPD).
Abstract: Nanostructured materials should present a good resistance to irradiation because the large volume fraction of grain boundaries can be an important sink for radiation-induced defects. The objective of the present study is to experimentally investigate the irradiation impact on the microstructure and mechanical properties in nanostructured materials. Nickel and Cu-0.5Al2O3 specimens were synthesized by electro deposition (ED) and severe plastic deformation (SPD). Mean grain size of the unirradiated specimen is about 30 nm for the ED Ni and about 115 nm for the SPD Ni. 590 MeV proton irradiation and 840 keV nickel ion irradiation were conducted at room temperature. Vickers hardness measurements and transmission electron microscope observation were performed to examine the impact of irradiation on nanocrystalline materials. It appears that the irradiation induced microstructure in Ni and in Cu-0.5Al2O3, which leads to hardening, consists exclusively of stacking fault tetrahedra. Their density appears much low...

TL;DR: In this article, an anisotropic continuum-based plasticity model is proposed to capture the large strain cyclic hardening behavior of magnesium alloys for both monotonic and reverse loading paths.
