In- and out-of-phase thermomechanical fatigue of a Ni-based single-crystal superalloy

Autor: Segersäll Mikael, Moverare Johan J., Leidermark Daniel, Johansson Sten

Publikováno v: MATEC Web of Conferences, Vol 14, p 19003 (2014)

In this study, the difference between in-phase (IP) and out-of-phase (OP) thermomechanical fatigue (TMF) cycling from 100 to 750 °C has been investigated for the Ni-based single-crystal superalloy MD2. In addition, two different crystal orientations

Thermomechanical fatigue crack growth in a cast polycrystalline superalloy

Autor: Moverare Johan J., Kontis Paraskevas, Johansson Sten, Reed Roger C.

Publikováno v: MATEC Web of Conferences, Vol 14, p 19004 (2014)

Thermomechanical fatigue (TMF) crack growth testing has been performed on the polycrystalline superalloy IN792. All tests were conducted in mechanical strain control in the temperature range between 100 and 750 °C. The influence of in-phase (IP) and

Simulation of oxidation-nitridation-induced microstructural degradation in a cracked Ni-based superalloy at high temperature

Autor: Yuan Kang, Peng Ru Lin, Li Xin-Hai, Johansson Sten, Wang Yan-Dong

Publikováno v: MATEC Web of Conferences, Vol 14, p 16004 (2014)

In turbine engines, high temperature components made of superalloys may crack in a creep process during service. With the inward flux of the gases, e.g. oxygen and nitrogen, along those cracks, the microstructure of the superalloy substrate nearby th
