20140170018 | ALUMINUM ALLOY INCLUDING IRON-MANGANESE COMPLETE SOLID SOLUTION AND METHOD OF MANUFACTURING THE SAME - Provided are an aluminum alloy including an iron-manganese complete solid solution and a method of manufacturing the same. According to an embodiment of the present invention, iron-manganese alloy powder is provided. The iron-manganese alloy powder is introduced into an aluminum melt. An aluminum alloy including an iron-manganese complete solid solution is manufactured by die casting the aluminum melt. | 06-19-2014 |
20130236351 | ALUMINUM-MAGNESIUM ALLOY AND METHOD OF PRODUCING THE SAME - Provided are an extruded aluminum (Al)-magnesium (Mg) material and a method of producing the same. An Al—Mg master alloy having a first Mg content is provided. An Al—Mg alloy having a second Mg content less than the first Mg content is prepared by adding the Al—Mg master alloy into molten Al and then casting the molten Al. An extruded Al—Mg material is prepared by extruding the Al—Mg alloy. | 09-12-2013 |
20120020829 | HEAT-RESISTANT ALUMINUM ALLOY AND METHOD FOR MANUFACTURING THE SAME - Disclosed is a heat-resistant aluminum alloy including aluminum and two types of alloy elements which are combined while forming a homogeneous solid solution reinforcing phase. The disclosed heat-resistant aluminum alloy includes the alloy elements that form a homogeneous solid solution and do not have a solvus line with respect to aluminum as a matrix metal and, therefore, the formed homogeneous solid solution reinforcing phase does not react with aluminum even at a temperature up to 300° C., thus not becoming coarse or undergoing phase decomposition. Consequently, the disclosed aluminum alloy may have remarkably enhanced heat resistance. | 01-26-2012 |
20110135812 | METAL SEPARATOR FOR FUEL CELL AND METHOD FOR TREATING SURFACE OF THE SAME - The present invention provides a metal separator for a fuel cell, which is surface-treated to have high electrical conductivity and electrochemical corrosion resistance, and a method for treating the surface of the same. The metal separator may include an amorphous carbon film formed on the surface of a separator substrate, the amorphous carbon film being carbonized by heat treatment to increase the proportion of sp | 06-09-2011 |
20100167141 | Apparatus and method for acceleratively activating fuel cell - Apparatuses and methods for accelerated activation of fuel cells are disclosed. The apparatuses include a fuel cell stack; an air supplying means coupled to a cathode catalyst side of the fuel cell stack through a mass flow controller and a humidifier; a hydrogen supplying means coupled to an anode catalyst side of the fuel cell stack through a mass flow controller and a humidifier; and a cable coupled to both ends of the fuel cell stack for short-circuiting the cathode and the anode. | 07-01-2010 |
