Abstract
The mechanical properties of Ni-Cr-Mo-based alloys with tailored ordered phases were investigated. Introduction of niobium induced the formation of a DO22 superlattice and stabilized this structure by avoiding its precipitation in ternary Ni-Cr-Mo. The tetragonal structure and high thermal stability of DO22 resulted in alloys with higher hardness (13â¯GPa) and the Youngâ²s modulus (225â¯GPa). Moreover, the sample containing the DO22 phase showed low creep strains and creep strain rates at holding time.
