Description
本実施形態に係るアルミニウム合金は、ケイ素(Si)が2〜6重量%、マグネシウム(Mg)が0.7重量%以下、残部がアルミニウム(Al)及び不可避な不純物から成る化学成分とされるとともに、成形性向上のために結晶組織が粒状とされた半溶融素材から得られるもので、熱伝導率が180W(m・K)以上とされている。
本実施形態に係るアルミニウム合金を得るためには、加熱工程S1、半溶融成形工程S2及び熱処理工程S3を順次行うものとされている。加熱工程S1は、アルミニウムにケイ素(Si)及びマグネシウム(Mg)を添加した合金を所定条件にて加熱することで、ケイ素(Si)が2〜6重量%、マグネシウム(Mg)が0.7重量%以下(0.2〜0.7重量%が好ましい)、残部がアルミニウム(Al)及び不可避な不純物から成る化学成分とされるとともに、結晶組織が粒状とされた半溶融素材を得る工程である。
下記の表1に示した成分を有するアルミニウム合金を加熱した後、所定の容器に注湯し、初晶α−Alが粒状になるように凝固制御を行ってビレットを作製するとともに、その作製したビレットを半溶融状態まで再加熱して円板状に加圧成形(半溶融成形)した。なお、マグネシウム(Mg)を溶解時に0.5%添加したもの、及び添加しないものをそれぞれ作製している。
S2 半溶融成形工程
S3 熱処理工程
