20130139564 | Method for increasing mechanical strength of titanium alloys having alpha" phase by cold working - A process for making an article of a titanium alloy having α″ phase as a major phase according to the present invention includes providing a work piece of a titanium alloy consisting essentially of 7-9 wt % of molybdenum and the balance titanium and having α″ phase as a major phase; and cold working at least a portion of the work piece at room temperature to obtain a green body of the article, wherein the cold worked portion of the green body has a thickness which is 20%-80% of that of the at least a portion of the work piece, and the cold worked portion has α″ phase as a major phase. | 06-06-2013 |
20130139933 | Method for enhancing mechanical strength of a titanium alloy by aging - A titanium-molybdenum alloy having α″ phase as a major phase is subjected to an aging treatment, so that yield strength of the aged alloy is increased by 10% to 120% with elongation to failure thereof being not less than about 5.0%. | 06-06-2013 |
20140081280 | METHOD AND APPARATUS FOR DELIVERING CEMENT PASTE INTO A BONE CAVITY - The present invention is related to a technique for simultaneously forming a plurality of paste filled tunnels. The plurality of paste filled tunnels are connected to a surgical tube directly or indirectly and emptied one after another, until a desired amount of the paste is injected into a bone cavity, organ or a tissue via the surgical tube. The paste may be a bone cement paste, a drug powder paste, viscous fluid or gel. The injected bone cement paste will set in the bone cavity to act as a medical implant. | 03-20-2014 |
