Nonlinear Field Theory of the Stress Induced Interdiffusion and Mass Transport

摘要

Constitutive equations for interdiffusion and mass transport induced by the stress gradient in crystal lattice is presented in terms of continuum thermodynamics. Only the standard balance laws are analysed for the mass, momentum, moment of momentum, energy and entropy. In consequence the driving forces for interdifl'usion of chemical constituents are determined, The forces depend not only on the stress gradient but also on the gradients of chemical components and temperature. The driving forces are used next in constitutive modelling of interdiffusion arid mass transport in crystal lattice.
