摘要：

A study was made of the structure and properties of hot-extruded quenched bars obtained from Duralumin DI ingots crystallized in a slip crystallizer and in an electromagnetic crystallizer. It is found that for all types of artificial aging employed (from 20 to 240 degree C) higher values of the strength properties are observed in bars obtained from DI alloy crystallized in the presence of a magnetic field. The type of crystallizer employed is also found to have an effect on the structure of artificially aged bars of DI alloy, a structure of twinning character being noted in the case of bars obtained from ingots crystallized in the presence of a magnetic field.
