Title: Method and apparatus for treating nonferrous metal alloy
Inventor: NINOMIYA SUSUMU
IPC: C21D9/573
Filed: 2002-10-22
Abstract: <P>PROBLEM TO BE SOLVED: To drastically enhance the strength of a nonferrous metal alloy more securely than heretofore.  <P>SOLUTION: At first, a nonferrous metal alloy is rapidly heated with liquid metallic sodium at about 450°C. Solid solution is formed over almost the whole composition in various alloy elements added to the nonferrous metal alloy, so that grading defects by the dislocation are largely formed inside crystal structures to suppress growth of the crystal grain size. Successively, the nonferrous metal alloy is rapidly cooled with the liquid metallic sodium at about 120°C. Crystal structures in the nonferrous metal alloy can be miniaturized while preserving grating defects generated in crystal structures of the nonferrous metal alloy. Also, the solid solution state itself becomes a supersaturated solid solution state in which segregation and concentration are suppressed in accordance with solute atoms in the solid solution. As the result of these effects, growth of the GP zone, in which solute atoms in solid solution are collected and deposited, is suppressed to make the nonferrous metal alloy extreamly high in strength.  <P>COPYRIGHT: (C)2004,JPO
