| 发明名称 | High performance nickel-based alloy | ||
| 摘要 | A nickel-based alloy includes, in weight percent, carbon from about 0.7 to about 2%; manganese up to about 1.5%; silicon up to about 1.5%; chromium from about 25 to about 36%; molybdenum from about 5 to about 12%; tungsten from about 12 to about 20%; cobalt up to about 1.5%; iron from about 3.5 to about 10%; nickel from about 20 to about 55%; and incidental impurities. The alloy is suitable for use in elevated temperature applications such as in valve seta inserts for internal combustion engines. | ||

| 主权项 | 1. A nickel-based alloy comprising, in weight percent: carbon from about 0.7 to about 2%; manganese up to about 1.5%; silicon up to about 1.5%; chromium from about 25 to about 36%; molybdenum from at least 6.5 to about 12%; tungsten from about 12 to about 20%; cobalt up to about 1.5%; iron from about 3.5 to about 10%; nickel from about 20 to about 55%; and incidental impurities, the alloy having an as-cast bulk hardness of over 52 HRc and a microstructure comprising eutectic reaction phases having a lamellar morphology and at least about 95 volume percent of the eutectic reaction phases and the microstructure is free of primary carbide phases. | ||
