Abstract
Description
(1)微細組織の構成
下記表2に示した各相の体積率およびサイズは以下のように推定したものである。
<体積率>
1)粗大粒アルミニウム相:試料のSEM像の面積率から画像解析ソフト(Gatan digitalmicrograph)を用いて推定した。
2)Al6Fe相: メカニカルアロイング後の粉末X線回折パターンを解析し、Alマトリックスに固溶しているFeの濃度を推定し、Al6Fe相の体積率を下記式1を用いて算出した。メカニカルアロイングの際にアルミニウム中に固溶したFeは全てAl6Fe相として析出すると仮定している。
(式1)
(式2)
全ての相において透過型電子顕微鏡像により解析した。
(2)メカニカルアロイングを施す時間
メカニカルアロイングの実施時間を60時間に設定した場合、No. 3(実施例1に相当)についての図3−4および6から明らかなように、延性を損なう原因となるナノ結晶相の集合体よりなる数十オm程度の粗大なAl13Fe4相が多く析出する。メカニカルミリングを行う時間が短いと、AlとFeの混合が十分に行われないために、FeまたはFe-richの金属間化合物相(AlFe相など)が形成し、焼結後、それらが粗大なAl13Fe4相となり、延性が損なわれる。一方、各相はナノスケールにまで微細化されるので、1GPaに近い高強度が発現する。
(3)メカニカルミリングの際に添加するエタノールの量
表1および2中のNos. 3および5の比較から確認されるように、メカニカルアロイングの時間を60時間に固定し、エタノールの添加量を4,8%と変化させた場合、室温における硬さおよび強度は、エタノールの添加量の増大とともに、上昇する傾向にある。このことから、添加量が多い方が、室温において高い強度を得るために効果的であると考えられる。メカニカルアロイングの時間を60時間より短時間または長時間行った場合にも同じ結果が得られることは推測可能であり、実際に、Nos. 6および8の比較ならびにNo. 12-14の比較から、メカニカルアロイングの時間を150時間および100時間に設定しても推測通りの結果が得られていることが確認される。
(4)放電プラズマ焼結時の温度および時間
焼結温度および時間については、高密度かつ高い強度−延性バランスを有する焼結体を得るために必要最小限とされる温度および時間を設定することが肝要である。
[表1]
表1および2のNo. 3が実施例1である。
[実施例2]
表1および2のNo. 6が実施例2である。
[実施例3]
表1および2のNo. 8が実施例3である。
[実施例4]
表1および2のNo. 13が実施例4である。

- 混在しているα-Al相の粗大粒の体積率が5%未満であることを特徴とする請求項1に記載の二元系アルミニウム合金粉末焼結材。
