A 50 mm x 50 mm bilayer plate is made by diffusion bonding a plate of pure Ni, 3 mm in thickness, to a plate of pure A12O3, 2 mm in thickness, at 827 °C. The isotropic properties of Ni are: ENi = 214 GPa, vNi = 0.31,

characteristics of Ni for the purpose of this problem.

(a) If the bilayer is uniformly cooled to room temperature (20 °C), what is the temperature at which plastic yielding begins during cooling from the bonding temperature?

(b) Is it possible to cause yielding of the entire Ni layer before reaching the room temperature?
