Abstract

The strengthening mechanism of 9Cr-1.5Mo-1Co and 9Cr-3W-3Co heat resistant steel was studied by tensile test and microstructure analysis. At the same temperature, the yield strength of 9Cr-3W-3Co heat-resistant steel is higher than that of 9Cr-1.5Mo-1Co heat-resistant steel. Microstructure analysis proved that the strength of 9Cr-1.5Mo-1Co and 9Cr-3W-3Co heat-resistant steel is affected by grain boundary, dislocation, precipitation, and solid solution atoms. The excellent high temperature mechanical properties of 9Cr-3W-3Co heat-resistant steel are mainly due to the solution strengthening caused by Co and W atoms and the high-density dislocations distributed in the matrix; however, 9Cr-1.5Mo-1Co heat-resistant steel is mainly due to the martensitic lath and precipitation strengthening.

摘要

通过拉伸试验和微观结构分析，研究了9Cr-1.5Mo-1Co和9Cr-3W-3Co耐热钢的强化机制。在相同温度下，9Cr-3W-3Co耐热钢的屈服强度高于9Cr-1.5Mo-1Co耐热钢。微观结构分析表明，9Cr-1.5Mo-1Co和9Cr-3W-3Co耐热钢的强度受晶界、位错、析出物和固溶原子的影响。9Cr-3W-3Co耐热钢优异的高温力学性能主要归因于Co和W原子引起的固溶强化以及基体中分布的高密度位错；然而，9Cr-1.5Mo-1Co耐热钢主要归因于马氏体板条和析出强化。
