Modeling of mechanical alloying: Part II. Development of computational modeling programs
Department of Materials Science and Engineering
Computational modeling programs incorporating the physics of powder deformation, fragmentation, and coalescence occurring during mechanical alloying (MA) are developed. The programs utilize the equations developed in part I of this series; equations predicting the extent of powder deformation during an effective impact in MA and those specifying criteria for powder particle fragmentation and coalescence. Two programs have been developed for these purposes. One, MAPI, considers the behavior of a single species with the option of adding dispersoids. The other, MAP2, considers two ductile species being welded to form a third, composite species. Applications of the programs to previous experimental data, and for the purpose of identifying the effect of material and process variables on alloying behavior, are provided in the article following this one.
