    Abstract: Lead and lead-alloy anodes for electrowinning metals such as zinc, copper, lead, tin, nickel and manganese from sulfuric acid solutions, whereby the electrodes are processed by a repetitive sequence of cold deformation and recrystallization heat treatment, within specified limits of deformation, temperature and annealing time, to achieve an improved microstructure consisting of a high frequency of special low .SIGMA. CSL grain boundaries (i.e. 50 %). The resultant electrodes possess significantly improved resistance to intergranular corrosion, and yield (1) extended service life, (2) the potential for reduction in electrode thickness with a commensurate increase in the number of electrodes per electrowinning cell, and (3) the opportunity to extract higher purity metal product.

    Abstract: Se revelan implantes m?dicos biodegradables in vivo que contienen en parte materiales met?licos con grano al menos parcialmente fino que son fuertes, duros, r?gidos, y ligeros. Los implantes biodegradables in vivo se usan en diferentes aplicaciones de endopr?tesis, para la fijaci?n de fracturas, suturas y los similares. Los implantes m?dicos biodegradables in vivo permiten la reducci?n del tama?o y el peso del implante y por consiguiente origina la reducci?n de la liberaci?n de los productos de degradaci?n del implante en el cuerpo.

    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: Recrystallized lead and lead alloy positive electrodes for lead acid batteries having an increased percentage of special grain boundaries in the microstructure, preferably to at least 50%, which have been provided by a process comprising steps of working or straining 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 cold work or strain, 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 electrodes during battery service, and result in extended battery life and the opportunity to reduce the size and weight of the battery.
