Introduction Composite materials Nb/Nb5Si3 have been extensively studied as the candidate materials of high temperature structural materials due to their high melting points and relatively low densities.
For isotropic materials, αV is approximately 3αl [26].
And for the anisotropic materials αV ≈ αa + αb + αc [26, 27].
