| 520 | 3 |a“In order to test the functioning of equipment, and to gain some initial experience concerning the environmental cracking susceptibility of Ti-7%Al-2%Nb-1%Ta (Ti-721) alloy, some tests were carried out on notched, precracked specimens loaded as cantilevers. In tests performed in 3.5% NaCl solution, it was confirmed that, subsequent to a sensitizing heat treatment designed to produce Ti3Al (8 hr at 650°C (1202°F)), alloy Ti-721 is extremely susceptible to environmental cracking. It is somewhat more resistant in the as-rolled condition. Environmental cracking tests in which specimens were broken under a gradually rising load were found to give very nearly the same results as did time-to-failure tests under a constant load. It appeared, therefore, that the rising-load method was sufficiently accurate for screening tests of alloys resembling Ti-721, though constant load tests might sometimes be needed for a more precise determination of the critical stress-intensity threshold for cracking, KISCC"--Abstract, p. i. |
