A study was made of the oxidation resistince of ten high-temperature alloys: (I) aluminum-modified Nichrome V, (2) Nichrome V, (3) niobium-modlfied Nichrome V, (4) am iron-chromium-aluminum alloy, (5) Inconel 702, (6) Hastelloy R235, F) Hastelloy W, (8) type 316 stainless steel, (9) Inconel X, and (10) In conel. Tests included the measurement of the average depth of external oxidation and raaximum depth of oxide penetration on specimens that had been subjected to stress in air at hlgh temperature for 100 hours, and on specimens that had been subjected to stress in air under fluctuating-temperature conditions for an equlvalent length of time, plus continuous recording of the weight change of specimens oxidized in air at high temperatures. The depth of oxidation was found to increase with temperature and wlth stress. There was little effect of stress at stresses below that required toproduce 1% extension in 100 hours. All of the alloys conformed reasonably well to the parabolic rate law in the welghtgain oxidation tests. (auth)
