Description Hot salt stress corrosion cracking (HSSCC) behaviour of alloy IMI 834 was studied to examine the effect of long-term exposure and the role of hydrogen. Studies were conducted by exposing the salt-coated specimens at 300, 350 and 400 degrees C, at different stress levels for 1000 h, and in the unstressed condition; and the role of hydrogen in HSSCC was studied by using X-ray diffraction. Although the specimens passed 1000 h of hot salt exposure test at stress levels higher than their yield strength, at these temperatures, the post-exposure tensile tests showed a significant loss in ductility and the presence of micro cracks. The study shows the presence of hydrides, which are responsible for HSSCC (C) 2015 Elsevier Ltd. All rights reserved.
