Title:
METAL MATRIX COMPOSITES WITH INTERMETTALIC REINFORCEMENTS
Document Type and Number:
WIPO Patent Application WO/2006/020607
Kind Code:
A3
Abstract:
A discontinuously reinforced metal matrix composite wherein the reinforcing material is a particulate binary intermetallic compound is described along with methods for preparing the same. The binary intermetallic compound includes the same type of metal as is the principal matrix metal in combination with one other metal. The particle size of the particulate binary intermetallic compound may be less than about 20 µm and may be between about 1 µm and about 10 µm. The intermetallic particles may be present in the discontinuously reinforced metal matrix composites in an amount ranging from about 10% to about 70% by volume. The discontinuous reinforced metal matrix composites of the invention may be used in structures requiring greater strength and stiffness than can be provided by matrix metal alone. The materials of the invention may be used for vehicle parts, structural materials, and the like.
