Unformatted text preview: Briefly explain. Y = Y(T) = Y o exp [E y /k B T] and Z = Z(T) = Z o exp[-E z /k B T] 3. Powder processing is often used to make ceramic parts. These, however, often contain significant amounts of porosity which can affect many important properties of the resulting ceramic piece. Imagine that a spherical ball bearing with a diameter of 1 mm is to be be made from spherical powder particles with a diameter of 10 m m. Calculate the volume fraction of porosity in the powder ball-bearing specimen prior to any compaction and sintering. Then, assuming a fully dense piece after compaction and sintering, calculate the percent shrinkage experienced along the ball bearing diameter assuming isotropic shrinkage....
