摘要: The formation of amorphous metallic systems by rapid quenching is influenced in a significant manner the detailed path corresponding alloy from melt through undercooled liquid down to state. thermodynamic history an system (quenching state with specific structure, interatomic bonding and short range ordering) forces template, reflecting presence ordered polyatomic clusters, into its potential energy structure. Subsequent transitions (nano)crystalline which then take place respect existing landscape such quenched-in local-scale heterogeneities. It will be shown that using model-free continuous approach for estimation distributions initial energetic states (reflecting cluster structure) it possible obtain information about types micromechanisms controlling transformation processes as well use this control phase selection during nanocrystalline A generalized view process nanocrystallization clustered presented. special focus put on nucleation methods their quantification. Two discussed.
