1. Material A and Material B are placed into metallurgical contact at a high temperature. Please sketch a concentration profile for each of the following scenarios: a. Assuming that this is a simple diffusion couple with immiscible solids and no intermediate phases, sketch a concentration profile for the diffusion couple at T. Use the simple binary phase diagram below. i. If J=108 and J=1012, what is the interfacial velocity? Make assumptions about the concentration values (given the phase diagram). In which direction is the interface moving and why? b. In the same scenario, sketch a new concentration profile assuming that an intermediate phase is present. Refer to the new phase diagram below at T. 1. Material A and Material B are placed into metallurgical contact at a high temperature.
