摘 要: 在分析了各種傳統(tǒng)金屬基復(fù)合材料制備方法的基礎(chǔ)上，提出了金屬基復(fù)合材料壓力下浸滲-半固態(tài)致密制備的新工藝，并利用該工藝成功地制備了Al2O3sf·SiCp/Al復(fù)合材料。結(jié)果表明：新工藝制備的復(fù)合材料的界面結(jié)合良好、組織致密、性能優(yōu)異；新工藝為金屬基復(fù)合材料壓力下浸滲半固態(tài)模鍛成形一體化工藝奠定了研究基礎(chǔ)。

Abstract: A new technology for metal matrix composites-infiltration-semi-solid densification under pressure based on the analyses of kinds of conventional metal matrix composites preparation methods was proposed. Al2O3sf·SiCp/Al was prepared successfully by this new technology. The results show that the interface bonding is very good, the structure is very dense and the performance is excellent. It establishes the study foundation for metal matrix composites prepared by infiltration-stamp forging in semi-solid state integral technology.
Key words: metal matrix composites; infiltration; semi-solid densification
