## Description

- description: Understanding the precise elastic modulus of individual γ and γ′ phases
    is crucial for estimating the elastic misfit between these phases, because it
    is a key factor in controlling the formation of raft structures and local stress/strain
    around γ′ precipitates. Despite its importance, research in this area remains
    limited. This study determines the elastic modulus of 6th generation Ni-base single
    crystal superalloy TMS-238 and its tie-lined γ and γ phases under equilibrium
    conditions above 900 °C. We fabricated TMS-238 and its tie-lined alloys with varying
    γ′ volume fractions. Using the rectangular parallelepiped resonance (RPR) method,
    we measured the elastic modulus from room temperature to 1100 °C. Elastic moduli
    between tie-lined phases were then estimated above 900 °C using composite models.
    Our findings were compared with those of Ni-Al binary alloys, Ni-Al-X ternary
    alloys, and multi-component systems, providing a comprehensive understanding of
    the elastic properties.
