| Summary: | Hastelloy S and Hastelloy C-4 subsize Charpy V-Notch (CVN) specimens that had been heated in air or vacuum at 600/sup 0/, 700/sup 0/, or 800/sup 0/C for up to 10,000 h were impact-tested at room temperature. No significant differences in Charpy impact energy were observed between the CVN specimens heated in air and the control specimens heated in vacuum. The CVN specimens aged at 600/sup 0/C showed the greatest reduction in Charpy impact energy, while the specimens aged at 800/sup 0/C showed the least change. Qualification testing of the as-fabricated prototype outer capsules was completed. The capsules passed all of the qualification tests without difficulty. The capsules subjected to the impact (drop) test showed some distortion at the weld area but passed the helium leak test. After the qualification tests were completed two of the capsules were subjected to additional external-pressure tests. The Hastelloy S capsule was pressurized to 24,000 psi (the limit of the autoclave) and showed only a slight distortion. The Hastelloy C-4 capsule collapsed at a pressure of 20,750 psi. Both capsules passed the helium leak check after pressurization. Two other capsules were subjected to an increased percussion test using an impact energy of 20 kg-m instead of the 7 kg-m used in the standard test. Both the Hastelloy S and Hastelloy C-4 capsules passed the more stringent test without difficulty. Nesdps Office Of Nuclear Energy Space And Defense Power Systems. |
