Doesn’t the stiffness decrease? Isn’t that how blacksmiths were able to form swords, by heating them up?

I'm asking this because I'm trying to find out what the speed of sound depends on.

I've figured out this far that it depends on the rigidity ("young's modulus") of the medium and the density.

However, now I just read that it also depends on the temperature, as vibrating molecules will have more energy to transfer onto each other.. this I do not understand.

So in case it does change.. is it because as you heat the metal it will also expand, causing the density to decrease, which should lead to a higher sound propagation?
