Environmental tests were made to determine the oxidation characteristics of various sheet materials which exhibited a strong potential for use in ramjet engine and/or heat exchanger structures. The sheet materials tested were Rene' 41, L-605, Hastelloy C, Types 316L and 321 stainless steel, 6061-T6 aluminum, and A110-AT titanium alloys. These materials were evaluated over anticipated service temperature ranges for 5, 25, and 50-hour oxidation exposure periods. Exposure tempera tures for the first five of these alloys were 1200, 1500, and 1800 F. For the last two alloys, the exposure temperatures were 350, 500, and 650 F; and 800, 1000, and 1200 F, respectively. Test specimen thicknesses ranged from 0.025 to 0.033 inch. |
