For a metal casting, what is the general effect of faster cooling on the solidification structure?

  1. A

    It generally produces a coarser solidification structure.

  2. B

    It generally produces a finer solidification structure.

  3. C

    It prevents grains and dendrites from forming.

  4. D

    It ensures that no residual stress or distortion can occur.

Select all statements that correctly describe a typical powder route for making ceramics.

  1. A

    A green body can be formed before the ceramic is fired.

  2. B

    Sintering requires the entire ceramic component to melt.

  3. C

    Sintering bonds particles and densifies the body without requiring the entire component to melt.
