We consider the phase transition of a string with tension {epsilon}{sub 1} to a string with a smaller tension {epsilon}{sub 2} at finite temperature. For sufficiently small temperatures the transition proceeds through thermally catalyzed quantum tunneling, and we calculate in arbitrary number of dimensions the thermal catalysis factor. At {epsilon}{sub 2}=0 the found formula for the decay rate also describes a breakup of a metastable string into two pieces.
