Controlled Diffusion Solidification (CDS) of Al-Zn-Mg-Cu (7050): Microstructure, heat treatment and mechanical properties

The tilt pour gravity casting process coupled with the Controlled Diffusion Solidification (CDS) process technology was employed to demonstrate the ability to cast AA7050 wrought alloy into high integrity near net shaped components with high strength and ductility. The CDS technology involves mixing two precursor alloys at different thermal mass and subsequently casting the resultant mixture into near net shaped cast components. The process …
