Abstract: Recrystallized lead and lead alloy positive current collectors and connectors such as straps and lugs for use e.g. in lead acid batteries and electrowinning anodes, having an increased percentage of special grain boundaries in at least part of the microstructure, which have been provided by a process comprising of (i) cold or hot rolling or cold or hot extrusion or (ii) steps of deforming the lead or lead alloy, and subsequently annealing the lead or lead alloy. Either a single cycle of working and annealing can be provided, or a plurality of such cycles can be provided. The amount of deformation, the recrystallization time and temperature, and the number of repetitions of such steps are selected to ensure that a substantial increase in the population of special grain boundaries is provided in the microstructure, to improve resistance to creep, intergranular corrosion and intergranular cracking of the current collectors and connectors during battery service, and result in extended battery life and the opportunity to reduce the size and weight of the battery.

Abstract: In-vivo biodegradable medical implants, containing at least in part at least partially fine-grained metallic materials that are strong, tough, stiff and lightweight, are disclosed. The in-vivo biodegradable implants are used in a number of stent applications, for fracture fixation, sutures and the like. The in-vivo biodegradable medical implants enable the reduction of implant size and weight and consequently result in reducing the release of implant degradation products into the body.

Abstract: Se describen los artículos poliméricos con chapa metálica que contienen recubrimientos metálicos de grano fino y/o amorfos, estructurales/capas que contienen opcionalmente partículas sólidas dispersas en éste. Los recubrimientos metálicos de grano fino y/o amorfos son particularmente adecuados para artículos fuertes y de peso ligero, moldes de precisión, artículos deportivos, partes automovilísticas y componentes expuestos a los ciclos térmicos, aunque el coeficiente de expansión térmica lineal (CLTE) de la capa metálica y el sustrato no sean similares. La interfase entre la capa metálica y el polímero es adecuadamente pretratada para resistir los ciclos térmicos sin falla.

Abstract: A surface treatment process for enhancing the resistance to intergranular corrosion and intergranular cracking of components fabricated from austeniti c Ni-Fe-Cr based alloys comprising the application of surface deformation to t he component, to a depth in the range of 0.01 mm to 0.5 mm, for example by high intensity shot peening below the recrystallization temperature, followed by recrystallization heat treatment, preferably at solutionizing temperatures. The surface deformation and annealing process can be repeated to further optimize the microstructure of the near-surface region. Following the final heat treatment, the process optionally comprises the application of further surface deformation (work) of reduced intensity, yielding a worked depth of between 0.005 mm to 0.01 mm, to impart residual compression in the near surface region to further enhance cracking resistance.

Abstract: Variable property deposit, at least partially of fine-grained metallic material, optionally containing solid particulates dispersed therein, is disclosed. The electrodeposition conditions in a single plating cell are suitably adjusted to once or repeatedly vary at least one property in the deposit direction. In one embodiment denoted multidimension grading, property variation along the length and/or width of the deposit is also provided. Variable property metallic material deposits containing at least in part a fine-grained microstructure and variable property in the deposit direction and optionally multidimensionally, provide superior overall mechanical properties compared to monolithic fine-grained (average grain size: >20 micron) or entirely amorphous metallic material deposits.

Abstract: Polycrystalline materials are prepared by electrodeposition of a precurso r material that is subsequently heat-treated to induce at least a threefold increase in the grain size of the material to yield a relatively high fracti on of 'special' low .SIGMA. grain boundaries and a randomized crystallograph ic texture. The precursor metallic material has sufficient purity and a fine -grained microstructure (e.g., an average grain size of 4 nm to 5 µm). The r esulting metallic material is suited to the fabrication of articles requirin g high mechanical or physical isotropy and/or resistance to grain boundary-m ediated deformation or degradation mechanisms.

Abstract: Fine-grained (average grain size 1nm to 1,000nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.
