摘要： Bipolar wave current, with both positive and negative current portions, is used to electrodeposit a nanocrystalline grain size deposit. Polarity Ratio is the ratio of the absolute value of the time integrated amplitude of negative polarity current and positive polarity current. Grain size can be precisely controlled in alloys of two or more chemical components, at least one of which is a metal, and at least one of which is most electro-active. Typically, although not always, the amount of the more electro-active material is preferentially lessened in the deposit during times of negative current. The deposit also exhibits superior macroscopic quality, being relatively crack and void free. Parameters of current density, duration of pulse portions, and composition of the bath are determined with reference to constitutive relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or, perhaps, a single relation showing grain size as a function of Polarity ratio.

摘要： Castable silicon-based compositions have enhanced toughness and related properties compared to silicon. The silicon-based compositions comprise silicon at a concentration greater than 50% by weight and one or more additional elements in structure comprising a cubic silicon phase and an additional phase which may impart toughness through mechanisms related to plastic flow or crack interaction with interfacial boundaries.

摘要： Al—Mnx/Al—Mny multilayers with a wide range of structures ranging from microcrystalline to nanocrystalline and amorphous were electrodeposited using a single bath method under galvanostatic control from room temperature ionic liquid. By varying the Mn composition by −1-3 at. % between layers, the grain sizes in one material can be systematically modulated between two values. For example, one specimen alternates between grain sizes of about 21 and 52 nm, in an alloy of average composition of 10.3 at. % Mn. Nanoindentation testing revealed multilayers with finer grains and higher Mn content exhibited better resistance to plastic deformation. Other alloy systems also are expected to be electrodeposited under similar circumstances.

摘要： Electrochemical etching tailors topography of a nanocrystalline or amorphous metal or alloy, which may be produced by any method including, by electrochemical deposition. Common etching methods can be used. Topography can be controlled by varying parameters that produce the item or the etching parameters or both. The nanocrystalline article has a surface comprising at least two elements, at least one of which is metal, and one of which is more electrochemically active than the others. The active element has a definite spatial distribution in the workpiece, which bears a predecessor spatial relationship to the specified topography. Etching removes a portion of the active element preferentially, to achieve the specified topography. Control is possible regarding: roughness, color, particularly along a spectrum from silver through grey to black, reflectivity and the presence, distribution and number density of pits and channels, as well as their depth, width, size. Processing parameters that have been correlated in the Ni-W system to topography features include, for both the deposition phase and the etching phase of a nanocrystalline surface: duty cycle, current density, deposition duration, plating chemistry, polarity ratio. The relative influence of the processing parameters can be noted and correlated to establish a relationship between values for processing parameters and degree of topography feature. Control can be established over the topography features. Correlation can be made for any such system that exhibits a definite spatial distribution of an active element that bears a predecessor spatial relationship to a desired topography feature.

摘要： Bipolar (pulse reversal) current, with both positive and negative current portions, is used to electrodeposit a nanocrystalline grain size deposit. Polarity Ratio is the ratio of the absolute value of the time integrated amplitude of negative polarity current and positive polarity current. Grain size can be precisely controlled in alloys. The deposit exhibits superior macroscopic quality, being relatively crack and void free. Parameters of current density, duration of pulse portions, and composition of the bath are determined with reference to constitutive relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio. The parameters can be used to select a specified grain size. Coatings can be in layers, each having an average grain size, which can vary layer to layer and also in a region in a graded fashion.

摘要： A mechanical structure is provided with a crystalline superelastic alloy that is characterized by an average grain size and that is characterized by a martensitic phase transformation resulting from a mechanical stress input greater than a characteristic first critical stress. A configuration of the superelastic alloy is provided with a geometric structural feature of the alloy that has an extent that is no greater than about 200 micrometers and that is no larger than the average grain size of the alloy. This geometric feature is configured to accept a mechanical stress input.
