Assist Prof. Dr. Mohsin AI- Yasiri 18. Spherical and ellipsoidal carbon nanomaterials are referred to as: (a) nanotubes, E fullerenes, (c) graphene, or (d) quantum dots. 19. The precipitation hardening via intermetallics in Fe-Ni superalloys is occurred due to presence of: (a) Mo and Cr, (6 Al and Ti, (c) W and Nb, or (d) Co and Cr. 20. The chemical formula of Gama Prime (y') phase in Ni-based superalloys is: (a) NijAl, (b) Ni3Ti, (c) Niz (Al, Ti), (d) Ni3Al, Ni3Ti, or Ni3 (Al, Ti), or (e) Ni3Al or Ni,Ti,. 21. It is a very expensive addition but leads to an improvement in the creep strength of Ni-based superalloys:(a Rhenium, (b) Hafnium, (c) Tantalum, or (d) Molybdenum 22. In shape memory alloys, the most common mechanism for lattice invariant shear during the growth processes of Martensitic Transformations is: (a) slip, (6) twinning, (c) both, or (d) none. 23. It is used for replacement of diseased and damaged parts: (a Cardiac pacemaker, (b) Orthodontic, (c) Catheters, or (d) Artificial hip joint. 24. MMCS reinforced with aligned fibers are stronger and stiffer when the direction of applied load is: (a) perpendicular to the direction of the fibers, (6 in the same direction of the fibers, or (c) no effect. 25. At elevated temperatures, nanophase ceramics are more: (a) brittle, (b) ductile, or ( no effect.
