Abstract: The fracture activation energy is determined from the stress dependences of the lifetimes of Al and $\alpha$-Fe measured at moderate and low test temperatures. The shear stresses are analyzed with allowance for the temperature dependence of the shear modulus and the athermal component of stresses.
