Conclusions 1. In the failure of discs caused by radial stresses we have established a strong influence of the temperature gradient along the radius on the reduction of the destruction speeds for various plasticity of the material. For δ = 0.5–6.0% a temperature gradient Δt = 755 °C reduced the destruction speed from 55,000 to 37,000 rev/min, i.e., 1.5 times. 2. The conclusions by the authors of a number of investigations about the small influence of Δt on nd of the disc are valid for a particular case, when the hoop stresses σθ determine the strength of the disc. 3. The procedure of elastic-plastic calculation of discs gives a good agreement between the calculated values of nd due to the centrifugal forces and Δt, and the experimental data. 4. Experimental work concerned with the study of the effect of a radial gradient Δt on the strength of discs of various configurations should be continued.
