More Information
Summary:A forming method wherein a billet (B, C) comprising a metal-based composite material prepared by mixing an aluminum alloy and a ceramic 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 height of the billet after the pressure forming. The above forming method allows the manufacture of a formed article having different volume contents 8Vf) of the ceramic for different portions thereof.
