Answer #1

A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point.Several key characteristics of a superalloy are excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation.

Many superalloys are produced using a two-phase heat treatment that creates a dispersion of cuboidal γ' particles known as the primary phase, with a fine dispersion between these known as secondary γ'. In order to improve the oxidation resistance of these alloys, Al, Cr, B, and Y are added.

1)Which of the following statements is true regarding aluminum / aluminum alloys ? Aluminum alloys are generally considered to be mechanically inferior compared to pure aluminum in terms of yield strength, because their microstructures contain precipitate phases that strain the lattice and therefore soften the alloy relative to pure aluminum. Aluminum is extremely rare in abundance within the earth's crust. Aluminum is very resistant to creep, because its ceramic (Al2O3) oxide layer thermally insulates the base metal and prevents grain...
