Abstract: A method of forming a wrought material having a refined grain structure is provided. The method comprises providing a metal alloy material having a depressed solidus temperature and a low temperature eutectic phase transformation. The metal alloy material is molded and rapidly solidified to form a fine grain precursor that has fine grains surrounded by a eutectic phase with fine dendritic arm spacing. The fine grain precursor is plastic deformed at a high strain rate to cause recrystallization without substantial shear banding to form a fine grain structural wrought form. The wrought form is then thermally treated to precipitate the eutectic phase into nanometer sized dispersoids within the fine grains and grain boundaries and to define a thermally treated fine grain structure wrought form having grains finer than the fine grains and the fine dendritic arm spacing of the fine grain precursor.

Abstract: Methods and compositions that serve to both darken a zinc or other active! metal surface and impart corrosion-resistant properties thereto, are disclosed. The compositions include an aqueous solution containing about 0.1 percent to about 5 percent ammonium chloride and about 0.1 percent to about 5 percent ammonium molybdate. The compositions utilize particular ratios of concentrations of ammonium chloride and ammonium molybdate.

Abstract: A rust inhibitor which ensures the simplicity of application typical for a coating process and can demonstrate excellent characteristics similar to those obtained with a metal spraying method. The rust inhibitor is manufactured by admixing zinc and aluminum as fine powders of inorganic metals, which are manufactured with a stamping mill to have a flaky shape, to a modified silicone resin solution. A silane-type silicone resin is used for the modified silicone resin solution. For example, a mixed solution of an organosilane-type silicone resin and an oligomer-type silane coupling agent and the like is used.

Abstract: Method for eliminating the precipitates contained in a II-VI solid semiconductor material by annealing, in which said solid semiconductor material is a congruent sublimation solid semiconductor material, and in which the following successive steps are carried out: the solid semiconductor material is heated under an inert gas flow up to a temperature T, between a first temperature T1, corresponding to the compound II-VI/element VI eutectic, and a second temperature T2, corresponding to maximum congruent sublimation temperature; the solid material is held at this temperature T under a neutral gas flow for a time period sufficient to eliminate the precipitates; the solid semiconductor material is cooled under an inert gas flow from temperature T to ambient temperature, at a rate such that, during cooling, the solid material merges with its congruent sublimation line; the precipitate-free solid semiconductor material is recovered.

Abstract: A process for producing implants made of a bioresorbable metal, particularly magnesium alloys or zinc alloys, in which the material properties of the magnesium or the zinc are changed and the processing and utilization properties are improved by combining process steps for adjusting the properties of the material and subsequent machining. In this way it is possible to produce thin-walled tubular implants, particularly blood vessel support stents, from bioresorbable magnesium or zinc alloys, which are readily deformable without the risk of fracture during implantation.
