IPC: C22C1/04
Filed: 2003-01-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for imparting excellent mechanical strength and thermal and electrical properties to a copper composite material.  <P>SOLUTION: An alumina (Al<SB>2</SB>O<SB>3</SB>) powder and a titanium boride (TiB<SB>2</SB>) powder are mixed with a base material (Cu powder), and the mixed powder is subsequently shaped into a primary shaped body and laterally squeezed to apply a strain corresponding to ≥200% elongation. Lateral squeezing is repeated for 12 times under a condition wherein the mold temperature is 400-1,000°C and the squeezing rate is about 1 mm/sec. Squeezing under this condition also serves as aging treatment, which facilitates deposition of the ceramic particles as well as miniaturization. This results in a secondary shaped product having average particle sizes of the base material (Cu) and the ceramic particles (Al<SB>2</SB>O<SB>3</SB>, TiB<SB>2</SB>) of ≤20 μm and ≤500 nm, respectively.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
