Description
1〜12mass%のアルミニウム及び0.2〜5.0mass%のカルシウム、残部マグネシウムから成る難燃性マグネシウム合金押出材の製造方法であって、
マグネシウム及び0.2〜5.0mass%のカルシウムを溶解した後、988K以上に昇温した上で1〜12mass%のアルミニウムを添加して溶解し、凝固させることを特徴とする。
本実施形態の難燃性マグネシウム合金としては、マグネシウム(Mg)と共に、少なくとも、1〜12mass%のアルミニウム(Al)及び0.2〜5.0mass%のカルシウム(Ca)を含有するものであればよく、その他に亜鉛(Zn)、マンガン(Mn)、ジルコニウム(Zr)、イットリウム(Y)、珪素(Si)から選ばれる0.01〜5.0mass%の添加元素を含有していてもよい。このようなものとしては、例えば、アルミニウム及びカルシウムを上記割合で含有するMg−Al系マグネシウム合金、Mg−Al−Zn系マグネシウム合金、Mg−Al−Mn系マグネシウム合金などが挙げられる。
〔実施例1〕
試料1として、純マグネシウム(Mg)1200gを700℃で溶解し、粒状の金属カルシウム(Ca)28.1gを添加して撹拌混合した。その後、溶湯温度を720℃まで昇温し、純アルミニウム(Al)76.6gを添加し、φ50×5t×230Lのパイプ状の金型内に鋳造した。図1は、試料1の断面を5%氷酢酸により8秒間(室温)のエッチングを行った場合の断面組織を示す顕微鏡写真図である。
実施例2は、実施例1において作製した試料1〜3に対して押出し加工を施し、その機械的特性を検証した。
下記表1は、試料1〜3を直径40mm、長さ40mmに切削加工した後、押出し比19.8、押出し温度400℃で押出し加工を施した場合の初期押出し力の測定結果である。
下記の表2は、試料1,3、及び試料2(比較材)を試料3と同じ条件で溶体化熱処理(T4)した試料4の引張り強さと伸びを示している。
実施例1と同様の方法で、直径170mm、長さ600mmの金型内に鋳造したものを、直径150mm、長さ410mmの6インチビレットに切削加工した後、1650tonの横型押出し機を用い、380℃において直径14mm(押出し比118)の丸棒に押出し加工したときの押出し力、最大押出速度を測定した。その測定結果を下記表3に示している。
