Write By Reza Haghayeghi : Enhanced refinement and modification via self-inoculation of Si phase in a Hyper eutectic aluminium alloy The alloy A390 was ultrasonically treated, and the resulting material was referred to as master alloy. The master alloy was added into a non-treated A390 melt over two different levels: 10 and 20% by volume in…
Writing By Reza Haghayeghi: The influence of intensive shearing above liquidus on the Solidification Process, microstructural evolution and its effect on the final Microstructure for the Al–10 wt% Mg alloy were investigated and discussed thor- oughly. The effect of shearing was explored and was compared with non-sheared samples. The effects of relaxation (holding melt after…
Reza Haghayeghi Abstract: The effects of ultrasonic treatment (UT) and electromagnetic stirring (EMS) forces, individually and in combination, prior to high pressure die-casting of AA5754 alloy were assessed. The liquid of alloy was subjected to UT, EMS and the combined style and then transferred to the shot chamber. The grain size, mechanical properties, gas content…
