The rate of a homogeneous nucleation of nanovoids in expanded aluminum is researched in this work. Typical lifetime of the system in a metastable state at a negative pressure as well as coefficients of surface tension and nucleation frequency at the temperatures 300 and 500 K are obtained with the help of molecular dynamic simulation. The large value of the pre-exponential factor should be noted, which requires further detailed investigations.
