Conclusions

The above-described investigation has demonstrated the feasibility of producing blanks of high density (up to 99% of theoretical) from atomized powders of various brass grades. Two production schedules can be employed, with or without a sintering operation preceding the hot forging of pressed blanks. However, if good mechanical properties are to be obtained in parts, use should be made of the former schedule. A high level of properties, particularly ductility, is attained at high initial compact porosities. It has been established that the sintering weight loss due to evaporation of zinc diminishes with decreasing zinc concentration in the powder and with increasing initial compact density. An empirical formula has been derived enabling the weight loss to be calculated for sintering under the conditions employed in this work.
