So in order to find the change of the diameter is it enough to say that : Δd= α*ΔΤ*d ?

Does Poisson's ratio apply when we have no loadings ? For instance if we have a free rod and we increase its temperature, in order to find the change of its diameter should i say : Δd=-v*ε_x*d, where d is the length of the diameter or Δd= α*ΔΤ*d ? Thanks in advance.
