The alloy may further be advantageously constructed to have a crystal structure selected from HCP, BCC, FCC, and tetragonal to further optimize the physical characteristics of the medical device.Type: ApplicationFiled: June 5, 2009Publication date: December 9, 2010Applicant: ABBOT CARDIOVASCULAR SYSTEMS, INC.Inventors: Pamela A.

Publication number: 20100272889Abstract: The present invention is directed to a process for the preparation of a metal powder having a purity at least as high as the starting powder and having an oxygen content of 10 ppm or less comprising heating said metal powder containing oxygen in the form of an oxide, with the total oxygen content being from 50 to 3000 ppmf in an inert atmosphere at a pressure of from 1 bar to 10?7 to a temperature at which the oxide of the metal powder becomes thermodynamically unstable and removing the resulting oxygen via volatilization. The metal powder is preferably selected from the group consisting of tantalum, niobium, molybdenum, hafnium, zirconium, titanium, vanadium, rhenium and tungsten. The invention also relates to the powders produced by the process and the use of such powders in a cold spray process.Type: ApplicationFiled: October 3, 2007Publication date: October 28, 2010Applicant: H.C.

Patent number: 7806995Abstract: A Mo—Si—B alloy has a matrix of Mo or a Mo solid solution, wherein 25% by volume to 90% by volume of molybdenum silicide and molybdenum boron silicide, optionally together with molybdenum boride, are incorporated. The alloy also contains 0.1-5% by volume of one or more oxides or mixed oxides with a vapor pressure at 1500° C. of <5×10?2 bar in finely dispersed form. The oxide addition not only improves the hot strength but also greatly improves the ductility.Type: GrantFiled: March 20, 2006Date of Patent: October 5, 2010Assignee: Plansee SEInventor: Pascal Jehanno
