摘要
核电的发展对材料提出了严格的要求。针对核电站反应堆压力容器用钢的国产化问题,本文综述了对国产第一炉20MnNiMo钢(相当于美国SA508—3钢)的显微组织的变化与强韧性和抗蚀性之间的关系,提出了相应的改进措施。
The development of nuclear power sets strictly de mands on materials.With a view to making reactor pressure vessel steel for nuclear power plantin China, the research results on the microstructure of the first heat20MnNiMo made in China (analogous to SA508-3 of U.S.A) have been Summa-riyeel.On the basis of the research the relationship between microstructureChange and properties (strength,toughness and corrosion resistance) has beenexpounded and the relevant measures for improving quality have beenproposed.
