Abstract

<p>JIS1種ならびに2種,3種,4種の工業用純チタンについて,高温(~300℃)・高圧(~75MPa)水素ガス中で低ひずみ速度引張試験(SSRT)を行った.測定した引張強度,伸び,絞りを,同じ温度で大気圧の大気中で測定した値によって規格化し,水素ガス中でのチタンの脆化の度合いを評価した.工業用純チタンは,その種別にかかわらず,75MPaの高圧水素ガス中でも引張強度が低下しないことが明らかとなった.100℃の高圧水素ガス中における伸びならびに絞りは大気中と比較し,むしろ増加した.</p>

<p>The slow strain rate testing (SSRT) on JIS Class 1, Class 2, Class 3, and Class 4 of commercially pure titanium (CP-Ti) was carried out in a hydrogen gas under high temperatures to 300℃ and high pressures to 75MPa. The degree of embrittlement in the hydrogen gas was evaluated from the tensile strength, the elongation and the reduction of area with respect to those measured in air at the same temperatures but under atmospheric pressure. It was revealed that the tensile strengths of the CP-Tis did not reduce regardless of their classes even in the hydrogen gas at a high pressure of 75MPa. The elongation and the reduction area at 100℃ rather increased in the high-pressure hydrogen gas than those in air.</p>
