Study of High-Temperature Alloy Creep and Calculation of Turbine Disk Life

摘要

We present the results of experimental study of creep characteristics of the VZhL12U and ZhS6U high-temperature alloys at working temperatures. We describe the three-dimensional simulation procedure of the stress-strain state taking into account variations in material resistance depending on the strain kind, acting loads and temperatures in time. We show the results of calculating the turbine disk and its bench fracture tests. The experimental and calculated data practically coincide.
