摘要：
The fatigue crack growth rates (FCGR) were measured in heat treated Inconel X-750 in air at temperatures from 25 degree C to 700 degree C in the range of frequencies from 0. 01Hz to 10Hz and compared with data obtained in annealed Inconel X-750 in the same test conditions. The fatigue crack growth rates increase when temperature increases and frequency decreases. The crack growth resistance at high temperature of the heat treated alloy is greater than the resistance of the annealed alloy in all the test conditions examined. The electron fractography of fatigued specimens shows a progressive change of the fracture mechanisms from a transgranular mode at 10Hz to an intergranular mode at 0. 01Hz. The role of oxidation and creep in increasing FCGR is analyzed and discussed in detail.
