Abstract
High-temperature fatigue properties of Alloy718 with different grain sizes were investigated. For the coarse-grain alloy, the fatigue strength notably decreased beyond 105 cycles. The fatigue fracture had originated from facets of the austenite grains. The facets caused a decreasing of fatigue strengths in a high-cycle region at high temperatures.
