Inconel718 process performance and requirements:
1
Due to Inconel718 alloy has a high content of niobium, and the degree of niobium segregation in the alloy is directly related to the gold treatment process

2
In order to avoid excessive element segregation in the ingot, the ingot diameter is adopted
