Abstract
Rapid Solidification Process (RSP) Tooling is a spray forming technology tailored for
producing molds and dies. The bines rapid solidification processing -shape
materials processing in a single step. The ability of the sprayed deposit to capture features of the
tool pattern eliminates costly machining operations in conventional mold making and reduces
turnaround time. Moreover, rapid solidification suppresses carbide precipitation and growth,
allowing many ferritic tool steels to be artificially aged, an alternative to conventional heat
treatment that offers unique benefits. Material properties and microstructure
