Journal of Mechanical Engineering| Summary: | The definition of coefficients for calculating the damageability parameter of billets from copper alloys using the Bailey-Norton and Rabotnov-Kachanov equitations on the basis of experimental data of billet creep in the temperature range of its viscous area, that is at 0.90...0.95 from liquidus temperature was considered. The experimental data were obtained on the AIMA 5-2 machine on the condition of its design improvement and testing method development. This allowed to determine the creep at the viscous area temperature of the billet from copper alloys at increasing the creep rate up to 1650...2500 times. The developed method for samples creep testing in the temperature range of the viscous area is protected by the patent ofUkraine№15924. The improved design of the AIMA 5-2 machine is protected by the patent ofUkraine№17741. As a result, the regulatory provision of the billet creep definition was developed in the form of the methods for carrying out tests on the improved AIMA 5-2 machine and the method for calculating damageability parameter of billets from copper alloys using the Bailey-Norton and Rabotnov-Kachanov equitations. |
