Forging and heat treatment method of high-temperature alloy and product thereof

The invention discloses a forging and heat treatment method of a high-temperature alloy and a product thereof, and belongs to the technical field of alloy forging. The alloy comprises the following components in percentage by weight: 21-24% of Mo, 7-10% of Cr, 5-8% of Wu, not greater than 2% of Fe, not greater than 0.8% of Mn, not greater than 0.5% of Al, not greater than 0.03% of C, and the balance Ni. The invention has the advantages that product manufactured by the method can reach the use temperature of 760 DEG C, is low in expansion and high in strength when being used at 760 DEG C, and effectively reduces the cracking risk of the alloy in the forging process under the high-temperature stretching state of 650 DEG C as follows: the tensile strength (MPa) is not less than 896, the yieldstrength (MPa) is not less than 552, the ductility (%) is not less than 13, and the section shrinkage (%) is not less than 16. 一种高温合金的锻造和热处理方法及其产品，属于合金锻造技术领域。合金组分按重量百分比计为：Mo：21-24，Cr：7-10，Wu：5-8，Fe：≤2，Mn：≤0.8，Al：≤0.5，C：≤0.03
