Behavior affected by K a stationary interface

If two materials meeting at an interface are subjected simultaneously to change of temperature and to a constrictive strain, can these influences be adjusted in such a way that no change of phase occurs  

if this condition can be attained, what processes or changes will occur  

It will be proposed that the two influences can be balanced and that, even without the interface moving, compositions in the two phases will become or will be nonuniform as elsewhere in nonequilibrium thermodynamics, a steady nonequilibrium condition can be maintained as long as a suitable flux of energy is driven through the system. 

Specifically, let phase g be the higher viscosity, lower-volume phase. Then, starting from an equilibrium condition, raising the overall pressure on the system will tend to make h convert to g. On the other hand, imposing a uniform constrictive strain rate will tend to make g convert to h, as in Chapter 13. If the two tendencies balance each other, an interesting condition will exist it is this condition that we wish to explore. 

To be specific, let the two phases coexist in equilibrium at some temperature 2 and uniform hydrostatic pressure P. Then let the temperature be kept at throughout, let the magnitude of be specified at any moment as + 3p, and let the imposed cylindrical constriction rate be Cq. Then in the equilibrium state (7, Pj), both eo and dp are zero but we envisage a series of nonequi-Ubrium stationary-interface states where e and dp balance each other, neither being zero. What will such a state be like and how might it be reached
