摘　　要：ERNiCrMo-3是一种特殊高温合金材料,其化学成分复杂。由于含有Mo、Nb等强化相元素,该合金锻造时的变形抗力大,锻造温度范围窄,再加上其导热性差,因此锻造成型难度较大。另外,如果坏料变形压缩量较小锻造后的铸造结晶组织就不易破碎,容易影响后续冷加工性能。本文从ERNiCrMo-3合金的化学成分、加热温度、锻造工艺、微观组织等方面开展试验来提高合金锻造性能,并应用于批量生产实践。ERNiCrMo-3 is a special super alloy with complex chemical composition.Since containing molybdenum,niobium,and other strengthening elements,the alloy has high deformation resistance,narrow forging temperature range and poor thermal conductivity,thus the forging of the casting ingot becomes more dificult.If the bllet deformation compression is light during forging,the inner casting structure is not easy to break.This phenomenon wllaffect cold working properties of the alloy.This paper proposes to improve the forging properties of ERNiCrMo-3ally by taking experiments on this alloy's chemical composition,heating temperature,forging process and micro-structure,and discusses the batch application of this method in production.
