Description
δ=(πfμσ)-1/2 ‥式(1)
のように表される。したがって、印加磁場の周波数を変化させることによって、粒子集積厚みを変化させることができる。このため、厚い集積層を得るためには、低い周波数の磁場を印加すれば良いと考えられる。しかしながら、周波数が低くなると金属融体の電磁攪拌が激しくなり、粒子集積を妨害する現象が現れるようになる。
図2に示す試験装置を用い、本発明に従って、SiC部分強化Al基複合材料を製造した。
コイル電流974A、電流周波数3kHzの交流電流を連続して30秒間通電することにより、磁場を連続して30秒間印加したこと以外は実施例1と同様の実験を行った。得られた材料の表面部(るつぼ壁面)付近の断面を顕微鏡により観察し、粒子集積層の厚さ及び粒子集積層中のSiC粒子の体積率を測定した。
