Abstract
Disclosed in a gas turbine nozzle having a superior thermal fatigue resistance. The gas turbine nozzle is made of a cast alloy consisting 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 0.1 wt % boron, 5 to 15 wt % of at least one of tungsten and molybdenum, 16 to 35 wt % cobalt and the balance nickel. The alloy has a heat-treated structure in which eutectic carbides and secondary carbides are dispersed in the matrix.
