Description
加工率P1(%)={(A0−A1)/A0}×100・・・(i)
加工率P2(%)={(A1−A2)/A1}×100・・・(ii)
(前提条件)Ti−Ni系合金の組成
下記に説明する実施例及び比較例は、Ti−51Ni(at%)の合金を用いて作製した。
(比較例1) 上記組成のTi−Ni系合金から線状の素材を切り出し、伸線加工を施して比較例1を作製した。線径は0.475mm、加工率は55%であった。
(a)試験方法
上記各比較例1〜7、及び、実施例1〜5をそれぞれ加工して、標点間距離が50mmの試験片を作製した。これらの各試験片をテンシロン型引張り試験機にセットして、室温でかつ1mm/minの試験速度で、引張り荷重を付与して伸び歪みを生じさせ、その後、引張り荷重を除去するというサイクルを繰り返して(荷重付与→荷重除去→荷重付与)、各試験片の引張り応力(MPa)とひずみ(%)との関係を測定した。その結果を、図3〜6及び下記の表1に示す。このときのヤング率を、ひずみ2%における引張り応力から算出した。
図3に示すように、伸線加工後に熱処理を施した場合(比較例2,3)、ヤング率は低下することが分かる。その傾向は熱処理温度が高いほど顕著である。図4に示すスエージング加工後の熱処理の場合も同じ傾向が確認される。
比較例1,4及び実施例1について、透過型電子顕微鏡(TEM)を用いて、その組織及び電子回折パターンを観察した。その結果を図7,8(実施例1)、図9(比較例1)、図10(比較例4)に示す。なお、実施例1については、2箇所の異なる位置でそれぞれ観察した(図7、8)。
(3)にて組織観察をした比較例1,4及び実施例1について、ビッカース硬さ(Hv)を測定した。荷重は200kgとし、各試料について組織外部と組織内部のビッカース硬さを測定した。その結果を図11に示す。

Claims (5)
- Ti−Ni系合金からなり、その線径が0.5mm以下で、ヤング率が50GPa以上とされ、伸線加工及びスエージング加工が施されたものであることを特徴とするガイドワイヤ用芯線。
- 前記Ti−Ni系合金の組織が微細結晶構造をなしている加工硬化型Ti−Ni系合金である請求項1記載のガイドワイヤ用芯線。
- 前記伸線加工及びスエージング加工に加え、熱処理が施されている請求項1又は2記載のガイドワイヤ用芯線。
- 請求項1〜3のいずれか1つに記載のガイドワイヤ用芯線の製造方法であって、
Ti−Ni系合金からなる素材を伸線加工した後、スエージング加工を施し、線径を0.5mm以下、ヤング率を50GPa以上にすることを特徴とするガイドワイヤ用芯線の製造方法。 - 前記スエージング加工後、更に熱処理を施す請求項4記載のガイドワイヤ用芯線の製造方法。
