what are the standard heat-treatment temperature and conditions for Inconel 718 alloy?
1st homogenization (heat-treatment temperature and process ?)
2nd solution Heat treatment and aging?
3rd Aging heat treatment
Dear Ajay kumar Maurya
You can find solid explanation for your query inside the attached file

Thaer F. A. Alsultan why sir? In additive Manufacturing, after preparing the samples/component using the technique such as DMLS, SLS. it is often required post processing activities such as heat-treatment, HIP to improve the mechanical properties...
Two heat treatments are generally utilized for INCONEL alloy 718:
1. Solution anneal at 1700-1850°F followed by rapid cooling, usually in water, plus precipitation hardening at 1325°F for 8 hours, furnace cool to 1150°F, hold at 1150°F for a total aging time of 18 hours, followed by air cooling.
2. Solution anneal at 1900-1950°F followed by rapid cooling, usually in water, plus precipitation hardening at 1400°F for 10 hours, furnace cool to 1200°F, hold at 1200°F for a total aging time of 20 hours, followed by air cooling.
If the material is to be machined, formed, or welded, it typically is purchased in the mill annealed or stress relieved condition. The material is then fabricated in its most malleable condition. After fabrication, it can be heat treated as required per the applicable specification.
