Room-Temperature Creep Testing of Grade 2 CP Titanium Plate Using Notch Tensile Samples

摘要

Commercially pure (CP) titanium has a unique behavior in that creep can occur at room temperature, which could be confused with hydrogen embrittlement under static loading conditions. This paper examines the effects of creep, hydrogen embrittlement, and notch sensitivity in Grade 2 CP titanium samples tested at room temperature. Fractographic characterization of the test samples was conducted to evaluate the operating failure modes and any notch effects.
