Effect of compositional modification on Young's modulus of Ti_2AlNb-based alloy

摘要

The Young's moduli of three Ti_2AlNb-based alloys were investigated. When they were heat treated to have a B2 single-phase structure, their Young's moduli were identical. In an O + B2 structure, the Young's modulus of O phase changed with alloy, and showed a correlation with the lattice parameter rate a/b.
