Publication number: 20090136379Abstract: A manufacturing method for wide-range fine-grained magnesium alloy thin-sheet material is disclosed. The method includes an extrusion process and a rolling process. By the plastic deformation feature of the two processes, the wide-range fine-grained magnesium alloy thin-sheet material that satisfies the requirement of cases of 3C products with thickness of less than 1 mm is produced. Thus the method overcomes shortcomings of a conventional method that produces the material by a plurality passes of processes. Therefore, the manufacturing cost is reduced and the method is able to be applied to various industries.Type: ApplicationFiled: November 28, 2007Publication date: May 28, 2009Applicant: CHUNG SHAN INSTITUTE OF SCIENCE AND TECHNOLOGY, ARMAMENTS BUREAU, M.N.D.Inventors: Shan Torng, Chune-Ching Young, Chia-Ming O, Wei-Pirn Hong

Publication number: 20090116992Abstract: A method for making Mg(magnesium)-based intermetallic compound uses a thermal process during a melting process to produce largely the Mg-based intermetallic compound. The vapor pressure of Mg is high, thereby Mg is prone to be vaporized from a melt and a wrought solid alloy in the melting process of high temperature, for purifying the wrought Mg-based intermetallic compound. The method may simplify the process and devices for making the Mg-based intermetallic compound, and produce efficiently a larger of high purity Mg-based intermetallic compound.Type: ApplicationFiled: December 10, 2007Publication date: May 7, 2009Inventors: Sheng-Long Lee, Jing-Chie Lin, Che-Wei Hsu, Cheng-Yu Chou, Yin-Chun Cheng, Chia-Wang Weng, Chien-Chang Chiang, Chien-Wei Chen

Publication number: 20080317621Abstract: An object of the present invention is to obtain an ingot containing homogeneous ingredients with suppressing ingredient segregation of Y in the melt-production of an Mg alloy containing Y. An ingot is formed in a solidification time of not more than 200 seconds after an Mg alloy containing Y is melted. The above solidification is desirably performed after the melt liquid of the Mg alloy is stirred and left standing. The above Mg alloy, for example, contains Y in an amount of 0.5 to 20% by weight. There is an advantage that an Mg alloy having low ingredient segregation and containing homogeneous ingredients is obtained. Therefore, in the production of alloys whose performance considerably varies depending on the ingredient concentration, such as functional materials, high-quality products can be produced in good yield rates. In order to achieve the above object, specifically, the raw material is melted in a melting furnace and, after melt drop, the melt liquid is sufficiently stirred and left standing.Type: ApplicationFiled: March 15, 2006Publication date: December 25, 2008Inventors: Yasuhiro Aoki, Hitohisa Yamada, Masahiko Muro, Yuuichi Ienaga
