A Monte‐Carlo simulation is made of the short‐range order in TaO with oxygen—oxygen long‐range strain‐induced potential with the exception of the first coordination shell. In a wide temperature range short‐range order of cluster type is discovered. On the basis of dislocation‐obstacle interaction models the start stress of (1/2)〈111〉{110} screw dislocations in the solid solution with clusters is calculated. Cluster nucleation leads to solution hardening.
