Casting of wrought alloys under external pressure

The paper presents results of wrought alloys casting trials under external pressure. Three alloys were used in the experiment - namely: 2024, 6061 and 7075. The examinations were conducted on squeeze cast parts that solidified under high pressure (150 MPa) in a Vertical Squeeze Casting machine UBE VSC 500. Gravity castings were used as a reference. The castings were heat treated to T6 condition. DSC and quantitative metallographic examinations were carried out. Mechanical properties were also tested. The advantageous effect of the external pressure has been assessed based on the results of the quantitative metallography and mechanical properties in cast and in the T6 condition.
