摘要: Abstract In this study, a comprehensive microstructure analysis was carried out to determine the solidification behavior of Inconel-713LC gas turbine blades under variety cooling conditions during electron beam welding (EBW). An empirical correlation between secondary dendrite arm spacing (SDAS) in fusion zone and rate established. Additionally, liquation observed heat affected (HAZ), which is induced by segregation elements at grain boundaries.
