Effect of microstructure on high-cycle fatigue properties of Alloy718 were investigated at 77 K by using samples with three different microstructures; fine-grained (FG), coarse-grained (CG) and bimodal-grained (BG) ones. The BG sample consisted of FG

A 2D dual pendulum thrust stand was developed to measure thrust vector of a Hall thruster without thermal effect. A thruster is mounted on a pendulum and gap sensors are mounted on the other. By measuring thrust from the displacement between two pend
