Abstract This paper presents the mechanical properties and curves of flows of alloys—solid solutions of systems copper-manganese, copper-aluminium and copper-nickel in temperature interval 4,2–1100 K. It shows that there are two athermic sections on the dependence σ0,2-T—by low and middle temperatures. Temperature dependence σ0,2 in the interval 77–293 K submits by the Feltham rule. The curves of deformation strengthening by temperature less 0.5 tmelt have three stages. The extent of the second stage of a plastic flow with almost constant coefficient of strengthening is increased both by raising concentration of alloyed element and by the fall temperature of a test. The raising of the temperature of deformation and diminution of concentration of alloyed element decreases the tension of transition to a third stage.
