Abstract
The process of mechanical alloying in binary metallic systems is discussed in a microscopic picture. Special emphasis is put on systems with large positive heat of mixing. In these systems, a competition between thermal diffusion and forced transport takes place. Based on results from Monte Carlo studies of the effect of combined shear and diffusion processes on an atomistic scale, a simple rate equation approach is developed. The approach can reproduce the phase evolution in the simulation and the main features of the temperature dependence of the alloy phase fraction in steady state. The results are further compared with experimental data.
