Powder metal (PM) technology delivers what no other process can: extreme alloy compositions and a refined microstructure that offer increased performance and longer useful lives in high-temperature and highly corrosive environments.
Since it was pioneered by ATI Allvac founder Jim Nesbitt and others, Vacuum Induction Melting, or VIM, has been utilized in the manufacture of high performance materials for critical service applications in a variety of industries. ATI Powder Metals couples this technology with inert gas atomization to supply homogeneous, pre-alloyed PM materials that could not be produced by alternative methods. Rapid solidification during atomization eliminates segregation during cooling and allows for increased alloy content versus conventional metallurgy. The resulting product exhibits a uniform microstructure that would not be attainable by the blending of elemental powders.
Whether 80,000 feet in the air or 40,000 feet underwater, the benefits of PM technology are readily apparent. PM superalloys, with an increasing ability to perform at higher operating temperatures, enable improvements in fuel efficiency of jet engines and power generation turbines. PM corrosion resistant alloys, or CRAs, extend service intervals in critical parts for oil and gas production, marine systems, nuclear power plants, and other highly corrosive, hard-to-service environments.
ATI Powder Metals supplies both solid and HIP-clad product forms, providing designers and engineers with a great deal of flexibility. Near-net-shape technology decreases rejection rates and reduces costs in complex highly-machined parts, while HIP-cladding can often eliminate the tradeoff that manufacturers are faced with when selecting appropriate materials for a given part by allowing utilization of multiple alloys.
