Mechanical properties and microstructure of thin plates of A6061 wrought aluminum alloy using rheology forging process with electromagnetic stirring (2013)
Presentation / Conference Contribution

We propose the possibility of fabricating A6061 thin plates using the rheology forging process. Electromagnetic stirring (EMS) is used to fabricate a semi-solid slurry. A thin plate is formed by injecting the slurry into the forging die. When the pun...
