Title | METALLIC FIBER THREE-DIMENSIONAL STRUCTURE HAVING HIGH POROSITY, AND METHOD FOR PRODUCTION THEREOF |
Abstract |
PROBLEM TO BE SOLVED: To provide a metallic fiber three-dimensional structure in which an intermetallic compound is formed on the contact part between metal fibers, and which has excellent shape memorizing properties and superelastic properties, and to provide its production method. SOLUTION: The metallic fiber three-dimensional structure is characterized in that a pure titanium fiber and a pure nickel fiber form a three-dimensional structure having a porosity of 40 to 95%, and also, an intermetallic compound is formed on the contact part between both the fibers. The production method uses the same. |
