Heat Treatment Effects on Pristine and Cold-Worked Thin-Walled Inconel 625

open access: yesMetals, 2021
Thin-walled Inconel 625 sheet metal was sectioned into tensile specimens, plastically strained, and then heat treated. Specimens were pulled to a targeted strain, unloaded, and then subjected to one of two heat treatments with the goal of restoring the ...
