Morphology and size effects on densification and mechanical behavior of sintered powders from Al-Si and Al-Cu casting alloys

The aim of this investigation is focused on the evaluation of the effect of two distinctive sizes and morphologies of powder particles from the recycled as-cast Al-Si and Al-Cu alloys. Elemental powders from Al-9Si, Al-5Cu alloys and a mixture 1:1 weight ratio between aforementioned casting alloys t...
