AI Technical Summary
Existing nickel-based alloy workpieces are prone to forging cracks and surface cracks during the forging process, especially the Inconel 625 alloy (UNS N06625).
The preparation method employs multiple heating, diffusion annealing, and post-forging residual heat annealing. This involves heating the nickel-based alloy in the range of 850-1050℃, performing diffusion annealing and forging, and then using the residual heat after forging for annealing. The heating rate and temperature gradient are controlled to reduce thermal stress, and the heating uniformity is ensured by using a load-bearing component.
It effectively avoids cracking and surface cracks during the forging process, improves the quality of forgings and material utilization, reduces energy consumption, and enhances the plasticity and toughness of materials.
