INVESTIGATION OF STRESS-CORROSION CRACKING OF HIGH-STRENGTH ALLOYS

Abstract

The accumulation of environmental stress-corrosion test data on the bent-beam and the U-bend test specimens was continued. Bent-beam specimens selected from the high-strength groups of all the alloys except Vascojet 1000 have undergone 51 days of testing in the more aggressive environments without failure. U-bend specimens have undergone 100 days of environmental testing. Based upon the data collected, the Vascojet 1000 alloy steel was the least resistant to stress-corrosion cracking. Preparations are being made for the testing of welded specimens and for testing of all the alloys in a solid-propellant environment.
