摘要：Disclosed is a gas turbine nozzle having a superior thermal fatigue resistance.The gas turbine nozzle is made of a cast alloy consisyting essentially of 0.1 to 1 wt%carbon, 0.1 to 2 wt% silicon, 0.1 to 2 wt% manganese, 20 to 35 wt% chromium, 0.001 to 0.1wt% boron, 5 to 15 wt% of at least one of tungsten and molybdenum, 16 to 35% cobalt

and the balance nickel. The alloy has a heat-treated structure in which eutectic carbidesand secondary carbides are dispersed in the matrix.
