Effect of high-temperature hot corrosion on the low cycle fatigue behavior of a directionally solidified nickel-base superalloy
Source abstract
Abstract
Abstract The low cycle fatigue behavior of a directionally solidified nickel-based superalloy DZ125 was examined at 850 °C in air using bare and salt-coated specimens. Experimental results show that the salt-coated specimen showed relatively low fatigue life compared with the bare specimen, and this effect accelerated with the increased applied maximum stress. Damage of hot corrosion in fatigue life was found to be associated with the reduction of the bare area and the early crack initiation from the weaken grain boundaries of recrystallized grains.
