Thixoforming of Wrought Aluminum Alloy 1973

Abstract:

In this paper, the microstructure and mechanical properties of thixoformed 1973 (AlZn5.5Mg2.4Cu1.7Zr) wrought aluminium alloy were investigated. A cooling slope was used to produce non-dendritic billets. Thixoforming process parameters were determined as follows: die temperature of 250 °C, feedstock temperature of 600 - 605 °C, punch velocity of 7 mm/s. Mechanical properties of thixoformed with ultimate strength of 461 MPa and elongation of 3,1 % in the T2 condition. The lower properties of the thixoformed material are mainly associated with porosity.
