Abstract: The present invention relates to a nickel-based super heat resistant alloy and a method of manufacturing the same. In the nickel-based super heat resistant alloy according to the present invention, an amount of solid solution strengthening elements (chromium, cobalt, molybdenum, or tantalum) is adjusted to improve a mechanical property, such as a creep property, at high temperatures, and aluminum or titanium is included in a predetermined amount to improve a corrosion property. The nickel-based super heat resistant alloy has excellent elongation, strength, and creep properties at normal temperature and high temperatures, and thus it is possible to manufacture parts of, by way of non-limiting example, a thermoelectric power plant, an aircraft, or a very high temperature reactor in various shapes on a large scale.

Abstract: The present invention relates to a nickel-based super heat resistant alloy and a method of manufacturing the same, and particularly, to a nickel-based super heat resistant alloy including 20 to 25 wt % of chromium (Cr), 10 to 15 wt % of molybdenum (Mo), 10 to 17 wt % of cobalt (Co), 0.01 to 0.15 wt % of carbon (C), 0.01 to 1 wt % of zirconium (Zr), 0.01 to 1 wt % of hafnium (Hf), 0.01 to 5 wt % of tantalum (Ta), 1 to 100 ppm of boron (B), 0.01 to 1 wt % of aluminum (Al), and a balance of nickel (Ni). In the nickel-based super heat resistant alloy according to the present invention, an amount of solid solution strengthening elements (Cr, Co, Mo, or Ta) is adjusted to improve a mechanical property such as a creep property at high temperatures and Al or Ti is included in a predetermined amount to improve a corrosion property.
