Superalloys - Characterization, Usage and Recycling

Superalloys are a group of alloys developed for use during long-term heat exposure above 650 °C. Properties and applications superalloys described in the present work. The work includes statis-tics about demand, market value current price. Division according to basic element is mentioned. Nickel-based further divided into two groups accord-ing their use. Afterwards, paper focused mainly on nickel-based superalloys. Examples listed Recycling possibilities stated analysed. General scheme processing superalloy scrap with regard content rhenium proposed shortly discussed. best-known companies dealing sup-eralloy recycling mentioned further.
