摘要 耐热钢是火电、核电、化工等领域中服役于高温条件下的关键材料,在服役过程中析出相的存在对耐热钢热强性、韧性、组织稳定性及抗高温氧化性等具有重要影响,而应变使基体中产生大量位错,对于析出相形核有促进作用。对耐热钢的主要合金元素和析出相进行了介绍,从应变诱导形核、应变诱导析出相长大和粗化、应变诱导析出模型的工程应用3个方面对耐热钢应变诱导析出模型的研究进展进行了综述,并对应变诱导析出模型的未来研究方向进行了展望。 Heat resistant steels are a key material serving in thermal power, nuclear power and chemical industry fields under high temperature conditions. The existence of precipitates during service has an important influence on the thermal strength, toughness, microstructure stability and high temperature oxidation resistance of heat resistant steels, and the strain causes a large number of dislocations in the matrix, which promotes the nucleation of precipitates. The main alloying elements and precipitates of heat resistant steels are introduced, and the research progress on strain induced precipitation model for heat resistant steels is reviewed from three aspects: strain induced nucleation, strain induced precipitation growth and coarsening, and the engineering application of strain induced precipitation model. The future research direction of the strain induced precipitation model is prospected.
