Abstract:

Strain rate sensitivity effects and strain hardening characteristics at room, elevated, and subzero temperatures were evaluated for a wide variety of both tough and brittle materials including 4340, 52100, and HF-1 steels, 6Al-4V and 6Al-6V-2Sn titanium alloys and the 8Mo-12Ti uranium alloy. Mechanical property parameters such as true stress, true strain, true fracture stress, ultimate and yield strengths, tension modulus, and reduction of area are examined under a temperature environment ranging from -116 deg C to 260 deg C over a strain rate spectrum of 0.001sec to 500sec.
