Characterization of the Effect of Melt Treatments on Melt Quality in Al-7wt %Si-Mg Alloys
The effects of degassing, holding time and melt additions (Sr, Sr + Ti, Ti, B and B + Sr) on the quality of A356 melts were examined. A total of 120 reduced pressure test samples were collected. Pores in these samples were ...
BIFILMS AND HOT TEARING OF Al-Si ALLOYS
(Shape Cutlng: 6th lntenudlmud Symposiam, Springer Link, 2016-01-01)
Hot tearing is one of the most interesting defects that can be found during casting of aluminium alloys. The definition of this defects has some uncertainties such as “it does not always appear under apparently identical ...
