Shape,
complexity, size and section thickness are the principal
variables that affect the MCF process, and its
suitability to manufacture a particular component.
Achieving detailed features in the part and tooling is
easily accomplished with the use of simulation based
design methods to balance the thermal mass and stress
pattern in various casting sections. Process simulation
is also possible to prevent alloy segregation in alloy
systems that have wide freezing ranges.
The MCF process offers the ability to form casting
as well as wrought aluminum alloys. In casting alloy
compositions the MCF process can typically produce
components with substantially better mechanical
properties than conventional casting methods (SEE TABLE
1). The improvements reflect the fine-grain structure,
excellent segregation, and elimination of microporosity.
While still under development, the MCF process also
exhibits strong potential for forming of wrought
aluminum alloys. Conventional precision forging achieves
mechanical properties which have longitudinal and
transverse variations, whereas the MCF properties result
from the fine cast microstructure produced by
pressurized solidification of the wrought aluminum
alloys.
