20100000702 | APPARATUS FOR DETERMINING THE HOT TEARING SUSCEPTIBILITY OF METALLIC MELTS - The present invention relates to an apparatus for determining the hot tearing susceptibility of metallic melts, comprising a casting mould, which has a first subvolume and a second subvolume, the second subvolume being formed as a tubular portion with a first end and a second end, the first end being connected to the first subvolume, comprising a measuring element, which extends into the second end of the tubular portion, and comprising a measuring device for recording a force on the measuring element and/or a change in position of the measuring element in the direction of extent of the tubular portion, the measuring device being coupled with the measuring element. The object of allowing an improved quantitative and qualitative determination of hot tearing susceptibility is achieved by the cross-sectional area of the tubular portion being reduced in the direction of the second end in each and every subportion of the tubular portion that may be selected substantially over the entire length. | 01-07-2010 |
20100054985 | CREEP-RESISTANT MAGNESIUM ALLOY - The present invention relates to a magnesium aluminum alloy with enhanced creep resistance. The alloy contains barium and calcium in low proportions, and possesses a higher creep resistance in comparison to alloys containing rare earth elements. The alloy may additionally include zinc, tin, lithium, manganese, yttrium, neodymium, cerium and/or praseodymium in proportions of up to 7% by weight, respectively. | 03-04-2010 |
20100274292 | PROCESS FOR PRODUCING COMPONENTS CONSISTING OF MAGNESIUM OR MAGNESIUM ALLOY BY SINTERING - The present invention relates to a process for producing components consisting of magnesium or magnesium alloy by sintering. This process makes it possible, for the first time, to produce components consisting of magnesium or magnesium alloy which provide outstanding elasticity together with a sufficient strength. Materials of this type can be used as biocompatible endosseous implant materials. | 10-28-2010 |
20110172724 | BIOCOMPATIBLE MAGNESIUM MATERIAL - A biocompatible material from which solid structures such as for example screws or plates can be manufactured, which are used for fixing bone fractures or damage and display an adequate mechanical stability. A mixture of apatite and a magnesium alloy, in the form of chips or powder, is ground in a ball mill until a homogeneous mixture forms. The homogeneous mixture is consolidated in a second step. This can be carried out by extrusion or forging. The desired shape can then be extracted from the obtained solid material by machining. | 07-14-2011 |
20110313527 | IMPLANT MADE OF A MAGNESIUM ALLOY AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to an implant from a magnesium alloy, in which porosity increases towards the core. | 12-22-2011 |
20120195787 | SINGLE-PHASE SOLID SOLUTION CAST OR WROUGHT MAGNESIUM ALLOYS - The present invention relates to single-phase solid solution magnesium alloys suitable for the applications as cast or wrought. These alloys are prepared by multi-microalloying with rare earth elements (including gadolinium, yttrium, dysprosium, samarium, lanthanum, cerium, neodymium and praseodymium). Each alloy contains 0.5 to less than 5 wt. % rare earth elements with a content of 0.05-2.0% by weight. The total amount of rare earth elements is controlled below 5% by weight in order for economical considerations. The amount of grain refiner calcium or zirconium is in the range of 0.05-0.6% by weight. These alloys can be prepared by die casting, permanent casting, chill casting, semi-solid processes, continuous casting and continuous twin roll casting. | 08-02-2012 |
20120195789 | MAGNESIUM-ALUMINUM BASED ALLOY - The present invention relates magnesium-aluminum based alloys having a small grain size and to a method of their production. The alloys are particularly useful in casting applications. The alloys comprise a grain refiner, the grain refiner having the chemical formula: | 08-02-2012 |
20140199365 | RESORBABLE STENTS WHICH CONTAIN A MAGNESIUM ALLOY - The present invention is directed to stents made of a magnesium alloy degradable under physiological conditions and an outer polymeric coating. Herein, the stents according to the invention can be additionally coated with at least one anti-inflammatory, antiproliferative, antiangiogenic, antirestenotic and/or antithrombogenic active agent. | 07-17-2014 |
20140222133 | MAGNESIUM ALLOY AND RESORBABLE STENTS CONTAINING THE SAME - The present invention is directed to a magnesium alloy comprising dysprosium, being degradable under physiological conditions and which is particularly suitable for the production of absorbable stents and to stents made thereof. | 08-07-2014 |
20150053364 | IMPLANT MADE OF A MAGNESIUM ALLOY AND METHOD FOR THE PRODUCTION THEREOF - The invention relates to an implant from a magnesium alloy, in which porosity increases towards the core. | 02-26-2015 |
