The supersymmetry (SUSY) self–consistent approximation for the model of non–equilibrium thermodynamic system with quenched disorder is derived by making use of generalized second Legendre transformation. The equations for adiabatic and isothermal susceptibilities, memory and field induced parameters and the temperature of ergodicity breaking transition are obtained on the basis of asymptotic an...

Isothermal crystallization studies were performed on the bulk glass forming alloy Pd40Cu30Ni10P20 in the undercooled liquid region between the glass transition and liquidus temperature, resulting in a complete time–temperature–transformation ~TTT! diagram for crystallization. The TTT diagram shows a typical ‘‘C’’ shape with the nose at 50 s and 680 K. Assuming steady state nucleation and a diff...

Due to the rapid cooling of the slag infiltrated into the mold-strand gap, it is expected that the rate of devitrification of the glass formed plays a key role in determining the proportion of crystalline phases influencing mold heat transfer. In this investigation, a novel procedure to calculate Time-Temperature-Transformation (TTT) curves of mold slags is presented. It is based on the integra...

This paper addresses a three-dimensional model for isothermal stress-induced transformation in shape memory polycrystalline materials in presence of permanent inelastic effects. The basic features of the model are recalled and the constitutive and the three-dimensional quasi-static evolution problem are proved to be well-posed. Finally, we discuss the convergence of the model to reduced/former ...
