Rapid Solidification Processing of Composites

Abstract

Rapid solidification techniques for producing laminated, particle- reinforced, and fiber-reinforced metal-matrix composites are discussed. Because the time for which the different phases of the composite are in contact at high temperature is limited to milliseconds, combinations of materials can be used which would react or degrade when held at these temperatures for the length of time required to form composites by conventional techniques. Rapid quenching to room temperature also allows the production of matrix alloys with non- equilibrium concentrations of elements. Subsequent segregation may improve matrix properties or improve the integrity of the bond at the matrix/ reinforcement interface. Additionally, RST is a commercially viable method for producing amorphous alloys in large volumes. (JES)
