The Influence of Orientation on the Fatigue of Directionally Solidified Superalloys
Directionally solidified (DS) nickel base superalloys were introduced to improve performance of jet engine turbine airfoils. The DS process imparts improved creep-rupture (1) and thermal fatigue (2) resistance in the solidification direction due to preferred crystallographic texture and grain boundary orientation, Figure 1.
