Abstract:
1. A method of fabricating an automotive engine component using dynamic magnetic compaction such that, upon formation, said component defines an exterior profile having axisymmetric and non-axisymmetric portions, said method comprising: providing a die having (i) a first part that defines a portion of an interior profile substantially similar to said axisymmetric exterior profile portion of said component; and (ii) a second part that defines a portion of an interior profile substantially similar to said non-axisymmetric exterior profile portion of said component; placing, within said first part of said die, a first material in powder form such that, when subjected to dynamic magnetic compaction, said first material defines at least a portion of said component corresponding to said axisymmetric exterior profile portion; placing, within said second part of said die, a second material such that, when subjected to dynamic magnetic compaction, said second material defines at least a portion of said component corresponding to said non-axisymmetric exterior profile portion; and forming said component from said first material and said second material using dynamic magnetic compaction; wherein said formed component is a substantially unitary structure defining an exterior profile having axisymmetric and non-axisymmetric portions.
