Abstract:The multivariate mixed Ag-Cu-Zn-Sn metal powder used in the preparation of cadmium-free silver-based intermediate temperature filler metal was investigated. The relationships among pressed compact density and the pressing pressure, pressing modulus and suppression rate were explored. Through the combination of theoretical analysis, experiments and software fitting curve research methods, the high rate pressure type equations under the conditions of electromagnetic compaction were built. A mathematical model and corresponding parameters for numerical analysis of electromagnetic compaction process are provided, the accuracy and reliability of the numerical simulation are improved. The results provide theoretical value and practical significance of engineering for designing the electromagnetic compaction process of the multivariate mixed metal powder in the Ag-Cu-Zn-Sn system.
Key words: electromagnetic compaction; metal powder; forming equation; pressed compact density
