Description
DSC(示差走査熱量測定)法により、変態温度(Ms)を測定した。測定条件は、−150℃から150℃までの昇降温速度を10℃/minとした。測定された変態温度について、310K(37℃)以下のものを超弾性発現の可能性ありとして優良(◎)と判定した。一方、変態温度が310K(37℃)を超えたものは不適(×)とした。
磁気天秤により各試験片の体積磁化率(Xvol)を測定した。測定条件は、室温とした。測定された体積磁化率について、水の磁化率(−9ppm)に対する偏差を算定し、±5ppm以下を優良(◎)とし、±15ppm以下を良(○)とし、±15ppmを超えたものを不適(×)と判定した。
各試験片について、ビッカース試験機(荷重300gf)によりビッカース硬度(HV)を測定した。評価については、300Hv以上を優良(◎)とし、200Hv以上を良(○)とし、150以上を可(△)とし、150未満を不適(×)と判定した。
各試験片について、圧縮試験機により圧縮ひずみ(ε)を測定した。測定条件は、室温で歪速度3.3×10−4s−1とした。評価については、εが10%以上のものを優良(◎)とし、5%以上のものを良(○)とし、5%未満のものを不適(×)と判定した。
