Answer» Right answer is (d) Nickel-based alloys Explanation: In the high temperature technology, the need for materials with superior strength, ductility and rigidity has been growing. Nickel-based alloys are the most widely used materials at the high elevated temperature, and super-alloys of it, are the greatest in the mechanical properties. |
