Flow Behavior and Hot Processing Map of GH4698 for Isothermal Compression Process [PDF]
Processes, 2019 An in-depth understanding of the flow behaviors of materials deformed at high temperatures is of paramount significance. However, insufficient research on the nickel-based GH4698 alloy has resulted in inaccurate material flow prediction or even cracking in the practical billet opening of GH4698 large forgings.
