摘要

Abstract

Interfacial β

phase strengthening on the creep properties of TNM alloy has been investigated. The initial fully lamellar microstructure with fine-dispersed interfacial β

phase was fabricated by powder hot isostatic pressing (P-HIP) and then carried out ageing treatment. The results indicated that the aged condition presented better microstructural stability and excellent creep resistance than the P-HIPed condition. Moreover

the ω phase precipitated within the β

phase by stress-inducing. The β

/β

(ω) phase was not only effectively restricted the dislocation motion

twins and stacking faults propagation

but also delayed the α

lamellae decomposition to maintain the integrity of the fully lamellar structure.
