Answer:- Option D
Single crystal turbine blades of nickel-based superalloys for aero engines are generally manufactured using DIRECTIONAL SOLIDIFICATION TECHNIQUE whereby the final component comprises only a single grain. The absence of grain boundaries in single crystal superalloys provides for superior creep and thermal fatigue resistance compared to polycrystalline alloys.
