Abstract
本発明を通じて開発された、新しいベータ系チタニウム合金は、既存に開発された生体医療用チタニウム合金に比べて弾性係数が非常に低く、いわゆる“応力遮蔽効果”の問題点を解決することができ、人工骨、人工歯、人工股関節などの人体医療用材料にはもちろん、メガネフレーム、ヘッドセットなどの一般民需用素材、レジャー用やスポーツ用素材にも広範囲に活用することができる素材である。
Description
以下において、本発明の好ましい実施例を通じて本発明をより詳細に説明する。しかし、下記実施例は、単に例示的なものであり、本発明を限定するものと解釈してはいけない。
本発明の技術的な目標を達成するための実施例として、Ti−Nb−Zrの3元系合金を下記表1のような組成で設計し、これを真空アーク再溶解方法(VAR)を用いて合金を製造した。
本発明の第2実施例では、人体に無害な元素を用いて、低弾性係数を保持するとともに機械的特性を向上させるために、下記表2に示したように、タンタル(Ta)をさらに添加して、上記第1実施例と同様に真空アーク再溶解方法(VAR)を用いて溶解し、インゴットを鋳造及び引抜きを行い、棒状に製造した。
Claims (5)
- 重量%で、ニオビウム(Nb):37〜41%、ジルコニウム(Zr):5〜8%を含有し、残りはチタニウムと不可避的な不純物からなり、弾性係数が55GPa以下であることを特徴とするチタニウム合金。
- 前記弾性係数が、50GPa以下であることを特徴とする請求項1に記載のチタニウム合金。
- さらに、タンタル(Ta)、ハフニウム(Hf)、モリブデン(Mo)、スズ(Sn)のうちから選択された1種または2種以上の元素が、3重量%以下で添加されたことを特徴とする請求項1に記載の低弾性係数を有するチタニウム合金。
- 前記ニオビウム(Nb)の含有量が38〜40重量%であり、前記ジルコニウム(Zr)の含有量が5〜7重量%であることを特徴とする請求項1又は2に記載の低弾性係数を有するチタニウム合金。
- 前記ニオビウム(Nb)の含有量が37〜39重量%であり、前記ジルコニウム(Zr)の含有量が5〜7重量%であり、さらにタンタル(Ta)を1〜3重量%含むことを特徴とする請求項2に記載の低弾性係数を有するチタニウム合金。
