讨论了在锻造过程中不同变形温度、变形程度对Rene′41合金组织和持久性能的影响。结果表明,Rene′41合金的锻造温度过高和锻压比低时,锻造过程中容易在晶界形成二次MC型薄膜状碳化物,影响后序的变形工艺;锻造时的过热也使合金在随后的时效过程中,在粗大晶粒上形成连续的M23C6型碳化物薄膜。晶界薄膜相严重影响Rene′41合金的持久寿命
The effects of different deformation temperature and degree of deformation on the microstructure and ductility of Rene’41 alloy during forging process are discussed. The results show that forging process of Rene’41 alloy is too high and forging ratio is low, it is easy to form secondary MC-type thin film carbides in the grain boundary during forging, which will affect the deformation process of the subsequent order. Overheating in forging also makes alloy Subsequent aging results in the formation of a continuous M23C6 carbide film on the coarse grains. The grain boundary phase severely affects the long life of Rene’41 alloy
