ABSTRACT:
Spray atomization of molten metal and/or intermetallic matrix composites reinforced with ceramic particles is practiced by atomizing the matrix into micron sized droplets and depositing the semisolid droplets in a bulk deposition upon a temperature controlled substrate. The semiliquid droplets are injected with refinement particles while in a range of 0 to 40% by volume solid phase and deposited on the substrate surface while in a 40 to 90% by volume solid phase. Refined grain morphology, increased solid solubility, nonequilibrium phases, absence of macro segregation, and elimination of the need to handle fine reactive particles are all achieved by performing the spray deposition process under a controlled atmosphere. Materials fabricated by the process exhibit unusual combinations of properties, such as spatially varying properties.
