High Temperature Low Cycle Fatigue of Co–Cr–Ni–W–Ta Heat Resistant Alloy Produced by Additive Technological Processes

Abstract—This article presents the results of fatigue tests of smooth cylindrical specimens while controlling full deformation under conditions of symmetric cycle and higher temperature. The interaction between material fatigue properties has been considered with consideration for stresses, plastic deformation, and number of cycles before failure. The deformation curves plotted by experimental data are compared with the deformation curves plotted by estimating methods.
