一种含锆镍基高温合金及制备方法
摘要：
本发明涉及一种含锆镍基高温合金及制备方法，所述镍基高温合金，以质量百分比计，包括锆：0.001％～0.1％，碳:≤0.1％，铬：12％～20％，钼：≤4.0％，钨≤6％，钴：5％～12％，铁：≤14％，铌：4.0％～8.0％，铝：0.6％～2.6％，钛：0.4％～1.4％，磷：0.003％～0.03％，硼：0.003％～0.015％，余量为镍；所述镍基高温合金的制备方法包括冶炼、锻造开坯和热处理过程。该镍基高温合金在保持高温强度基本不变的情况下，能够明显提高合金的持久寿命，并能够有效改善合金的热加工性能，在700℃条件下能够长期使用。
摘要（英）：

The invention relates to zirconium-containing nickel-based superalloy and a preparation method thereof. The nickel-based superalloy comprises the following components in percentage by mass: 0.001%-0.1% of zirconium, less than or equal to 0.1% of carbon, 12%-20% of chromium, less than or equal to 4.0% of molybdenum, less than or equal to 6% of tungsten, 5%-12% of cobalt, less than or equal to 14% of iron, 4.0%-8.0% of niobium, 0.6%-2.6% of aluminum, 0.4%-1.4% of titanium, 0.003%-0.03% of phosphorus, 0.003%-0.015% of boron and the balance of nickel. The preparation method of nickel-based superalloy comprises the processes of smelting, hammer cogging and thermal treatment. According to the nickel-based superalloy, the endurance life of alloy can be obviously prolonged when the high-temperature strength is basically unchanged, and the hot processing performance of the alloy can be effectively improved; the nickel-based superalloy can be used at 700 DEG C for a long time.
