Title:

METHOD FOR MANUFACTURING FORMED ARTICLE MADE FROM METAL BASED COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2005/068106

Kind Code:

A1

Abstract:

A forming method wherein a billet (31, 66, 77, 87, 107, 128, 136, 144, 153, 77B, 77C) comprising a metal based composite material (27) prepared by mixing an aluminum alloy (22) and a ceramic (15) is subjected to pressure forming to manufacture a formed article, which comprises carrying out the pressure forming by the use of different compression ratios for different portions of the formed article, wherein a compression ratio means the ratio of the height of a billet before the pressure forming to the height of the billet after the pressure forming. The above forming method allows the manufacture of a formed article having different volume contents (Vf) of the ceramic for different portions thereof.
