An isothermal model for creep rupture prediction of equiaxed gas turbine airfoils is presented. It provides a family of curves linear in log-log space between applied tensile stress and rupture time. Each curve represents a specific temperature. The

An innovative procedure is presented here for determining the minimum low cycle fatigue (LCF) life of turbine disk bores under multiaxial states of stress. The procedure statistically combines multiaxial data from spin pit tests with the data from un

The fatigue lives of modern powder metallurgy disk alloys can be reduced over an order of magnitude by cracking at inherent non-metallic inclusions. The objective of this work was to study the effectiveness of shot peening in suppressing LCF crack in

In a previous paper, a criterion for multiaxial lifing of turbine disk bores made from a nickel base super alloy, DP-718, was substantiated using results from spin pit testing of mini disks. In this paper, another turbine and compressor disk alloy, A
