Modeling of mechanical alloying: Part III. Applications of computational programs

The computational modeling programs described in part II of this series are used in two ways. One is to compare program predictions to previous experimental data, thereby testing to some extent the utility of the programs. At this stage of their development, program “predictions” with respect to processing time, microstructural scale, and similar parameters are accurate to within a factor of 2 or so. Even so, the predictions offer support of the model developed in part I of this series and provide a vehicle for both model and process refinements. In addition to “testing” the model and the program in these manners, the effect of uncertainty in input material properties on program predictions is explored.
