Superficial expansion is defined as the increase in surface area of the solid on heating. Thermal expansion relates with the expansion and contraction of particles in a substance function of temperature. Full thermodynamic equilibrium values of volume fraction of martensitic phase zeq corresponding to ɛ T values of external state parameters can be determined with the formula z eq kLɛ aT T 0 rp 1 20 ϕ it kLk 2rϕ it obtained from 314 after simple manipulations.
