WebDec 21, 2024 · The average grain sizes in the HAZ of Inconel 718 and of Inconel 600 were found to be 359 ± 127 µm and 268 ± 86 µm, respectively. During friction welding, intense heating occurs at the weld interface and high temperatures (close to 0.8 T m) are attained. As a result, some grain growth occurs in the HAZ [ 18 ]. WebInconel is a family of austenitic Nickel-Chromium based alloys. Inconel chemical etching is a great process for harsh environments subjected to extreme pressures and temperatures. It forms a thick and stable oxide layer that protects its surface from attack when it is heated. The alloy retains strength over a wide temperature range and exhibits ...
