It is shown that cryogenic deformation (77 K) speeds up the kinetics of particle precipitation in the second phase, using the subsequent heat treatments in order to form the structure with increased volume contents of α-phase. Studied is the microst

The stability of rock masses is important in the planning, construction, and exploitation of underground structures. Several attempts have been made to assess stability. They have been based mainly on information from visual observations of the behav
