- Abstract
A microstructural analysis of Inconel 718 tube flow forming is presented. The grain fragmentation analysis shows that the increase of the number of reduction passes allows a more homogenous distribution of strain which may explain the higher ductility observed when the number of reduction passes increases. Additionally, recrystallized grains and δ phase volume fraction increase were observed. This observation indicates a temperature increase and a very high increase of the δ phase precipitation kinetics.
