Modelling the Impregnation of a Pressure-Tight Casting

Abstract Pressure tightness is important for many die-cast aluminium castings, but the interconnected porosity formed in the aluminium alloy high-pressure die castings (HPDC) can form a network connecting several surfaces of the casting, especially as a result of machining after casting. The resulting potential leakage path can be imagined as a series of discontinuities varying in

High-Pressure Die Casting of Al–Ce–La–Ni–Fe Alloys

High-Pressure Die Casting of Al–Ce–La–Ni–Fe Alloys

Benjamin E. MacDonald1, Stuart Wiesner2, Ryan Holdsworth1, Carl Söderhjelm1 & Diran ApelianORCID:orcid.org/0000-0001-9743-606X1 Abstract The effects on phase equilibria of La and Fe additions to the Al–Ce–Ni-based alloy system are explored under high-pressure die casting conditions. The addition of La to Al–Ce–Ni-based alloy system only reacts with Ce synergistically to promote the formation of the Al11(Ce,La)3 intermetallic phase as predicted by CALculation

The specimen was fixed by four fixtures, where two outer fixtures were connected to upper moveable shaft for applying the loading. The two internal fixtures were connected to the fixed base in the bottom. Between the fixture and the shaft/base were thin steel spring to ensure that the specimens can bend flexibly. To show the details more clearly, the distance between each fixture shown in the picture is larger than the actual distances used in this study.
