Bulk microstructure evolution of two high Hf–containing nickel–based alloys during exposure at temperatures from 1100 to 1250°C [PDF]
Two Hf–poorest versions of a high performance chromia–forming nickel–based polycrystalline cast alloy reinforced by HfC carbides were investigated by replacing more or less hafnium by tantalum to reduce production cost.
