Bumgartner,

Static fatigue crack velocities were measured in two types of titanium diboride under conditions existing in aluminum reduction cells. Double torsion specimens were heavily loaded (up to K/K /SUB lc/ = 0.85) for extended times at 960/sup 0/C while subjected to environments of aluminum, electrolyte, or electrolysis. Within the sensitivity limits of the method (about 10/sup -10/ m/s), one material did not exhibit slow crack growth. In the other material, crack velocity increased under cathodic conditions as compared to the rate in aluminum without electrolysis.
