  • Publication number: 20150050157
    Abstract: Ni base superalloys containing relatively large amounts of Al and/or Ti are known to be difficult to weld satisfactorily. As the Al and Ti content of the superalloy is increased to improve the strength, the weldability of the component is drastically reduced. It is concluded herein that reducing the ?? phase improves weldability. A stepwise, controlled heating and cooling process is described to be used in cooperation with a welding process to reduce the ?? present and thereby improve weldability.

  • Patent number: 8920866
    Abstract: A metal implant, in particular a dental implant, with a hydrophilic surface for at least partial insertion into a bone, and a method for the production of said implant are described. A particularly advantageous hydrophilic surface for improved osteointegration properties is made available if it is briefly treated, at least in some areas, in a weakly alkaline solution. These excellent osteointegration properties can be achieved in a method in which, optionally after a preceding mechanical surface modification by material removal and/or chemical surface modification, at least the areas exposed of this surface exposed to bone and/or soft tissue are chemically modified in an alkaline solution.

  • Patent number: 8910368
    Abstract: In order to sharpen and harden a corner portion of a score line edge portion of an iron golf club having a plurality of score lines on a face surface within a prescribed range, heat input is implemented on an edge portion of a groove through laser irradiation after the groove is machined and, as a result, the edge portion is hardened and melted to form a rounded corner R. The hardness is set at a Vickers hardness value (HV) of at least 350. The corner R forms a part of a contour line of the edge portion and this contour line is formed to exist between a first circle that contacts the face surface and a side surface of the groove and has a radius of 0.010 inches (0.254 millimeters) and a second circle that is concentric with the first circle and has a radius of 0.011 inches (0.2794 millimeters).

  • Patent number: 8813360
    Abstract: In a method for beam welding on components with a laser beam or electron beam generated by a beam source, the heat treatment of the welded component required to remove stresses is integrated into the welding process. In a work cycle combined with the welding process, a regulated heat supply to a selected region takes place, according to its residual heat resulting from the welding process and the predicted stresses in that region, using the residual heat remaining from the welding process following the welding process from the same or other beam source(s). The welding region is cooled in a controlled manner, so that welded components which are likely to be subject to high stress in use, provided for example for a aircraft engine, can be made available without inherent stresses and with the desired microstructure in a single—combined—work step.

    Abstract: A process of irradiation Sn containing Pb-free solder to mitigate whisker formation and growth thereon is provided. The use of gamma radiation such as cobalt-60 has been applied to a substrate of Sn on copper has been found to change the morphology of the crystalline whisker growth to a more truncated hillock pattern. The change in morphology greatly reduces the tendency of whiskers to contribute to electrical short-circuits being used as a Pb-free solder system on a copper substrate.
