Abstract
【解決手段】ニオブ中の酸素含量が3000〜30000μg/gであり、空気中5ミリバール以下、600〜800℃の温度で処理し、酸素含有量を増加させ室温にて引き延ばして線材にする。
【選択図】なし
Description
前線材の形でニオブを600〜800℃の温度範囲内で5ミリバール未満の範囲の圧力で空気に接して、同時に進行する拡散工程によって酸素含量の増加がバルク中にまで生じるように酸素を負荷する。3000〜30000μg/gの酸素含量を有するニオブ合金が生じる。こうして製造されたニオブ合金を室温で0.2〜0.4mmの直径範囲内の線材に引き伸ばす。
Claims (9)
- ニオブ線材において、酸素含量が増加されていることを特徴とする、ニオブ線材。
