MATERIALS INVESTIGATION, SNAP 50/SPUR PROGRAM. PART I. CREEP RUPTURE PROPERTIES OF STRESS-RELIEVED TZM ALLOY

Abstract

The results of experimental investigations to determine the effect of potassium on the creep-rupture properties of the TZM alloy are presented herein. The tests were conducted at 1800 and 2000F, with and without exposure to saturated potassium vapor. The results indicated that the creep-rupture behavior was not influenced significantly by exposure to potassium vapor for periods of approximately 1,000 hours. However, some mass-transfer type corrosion was observed. This signifies that it is dangerous to extrapolate the results of this study to 10,000 hours, because progressive mass transfer might eventually cause accelerated creep and premature failure.
