Abstract
Description
に役立つ、高強度で延性特性を有するCo系アモルファス合金に関する。

サンプル作製
母合金は、アルミナまたは石英のるつぼで、純Co、Fe、Cr、Ni、Mo、黒鉛(99.9wt%)とCo80B20のプレ合金(99.5wt%)の混合物を誘導溶解して作製した。必要に応じて、インゴットはアーク溶融して均質化した。次いで、シングルローラー溶融スピナーを用いてチルブロック溶融紡糸(CBMS)法で、母合金から厚さ55〜160μm、幅1〜5mmの薄帯を製造した。プロセス雰囲気は不活性ガスまたはCO2であった。一般に、薄帯の厚さt>100μmでは、ホイール速度≦13mm/sを適用する必要があった。
薄帯の熱的特性、構造特性、機械的特性を、20K/minの一定の加熱速度と精製アルゴン流下で示差走査熱量測定(DSC)によって、またX線回折分析、光学立体視法、機械的試験によって評価した。X線測定は、Co−Kα放射線を用いた反射形態で、2θ=20〜80度または10〜100度の範囲で実施した。
HV(GPa)=0.92671HIT
以下の表1は、真空/アルゴン雰囲気(室圧300mbar)中で処理し、試験したCo−Mo−C−B−Xの鋳放しの薄帯の一覧である。合金組成は、比較例と、本発明による実施例を含む。比較合金のCr含有量は5〜15原子%であり、合金はさらに、5原子%のFeを含有してもよい。本発明による合金は、FeおよびCr含有量を減らし、さらに抑えて、延性を改善すると同時に、以下に示すように高い破断強度を維持する。
