Book Description
From 1999 to 2006, a program was undertaken within the Materials Science and Technology Division, formerly the Metals and Ceramics Division, of Oak Ridge National Laboratory to characterize the tensile and creep-rupture properties of a newly produced heat of Haynes alloy 25 (L-605). Tensile properties from room temperature to 1100 C were evaluated for base material and welded joints aged up to 12,000 hours at 675 C. Creep and creep-rupture tests were conducted on base metal and cross-weldments from 650 to 950 C. Pressurized tubular creep tests were conducted to evaluate multiaxial creep-rupture response of the material. Over 800,000 hours of creep test data were generated during the test program with the longest rupture tests extending beyond 38,000 hours, and the longest creep-rate experiments exceeding 40,000 hours.

Book Description
The creep of Haynes Alloy 188 sheet in air was studied at temperatures of 790, 845, and 900 C for times in excess of 30,000 hours as part of a program to assure that Haynes Alloy 188 could be used in critical components of a solar dynamic power conversion system for Space Station Freedom. The rupture life and time to 0.5 and 1.0% creep strain of creep rupture specimens which had lives from about 6000 to nearly 59,000 hours are reported. Both welded and as-received specimens were tested. The welded specimen had essentially the same lives as the as-received specimens. Comparison of this data with previously published results suggests that this material was similar in behavior to that previously studied by Haynes except at 790 C where the current sheet is somewhat stronger in stress rupture. Therefore the previously published data for Haynes Alloy 188 may be used in conjunction with this data to estimate the lives of components for a long life solar dynamic power system. Three creep rupture tests were discontinued after 16,500 to 23,200 hours and tensile tested at room temperature or 480 C. The elongation of all three specimens was substantially reduced compared to the as-received condition or as aged (without applied stress) for 22,500 hours at 820 C. The pores found across the thickness of the interrupted creep specimens. The implications of the severe loss of ductility observed in tensile tests after prolonged creep test needs further study.
