A holistic approach to Thermo-Mechanical Fatigue phase angle effects for an aerospace nickel superalloy

Thermo-Mechanical Fatigue (TMF) is one of the most complex mechanical phenomena that couples creep, fatigue and oxidation. So far, developing simple empirical relationships like those that exist in isothermal equivalents have proven elusive. This work presents a study on the TMF behaviour of the aerospace nickel based superalloy RR1000 using TMF fatigue crack growth rates, strain controlled TMF results, studies of the fracture morphologies and...
