On-Site Speaker (Planned) Alex Xie
Abstract Scope Pure molybdenum and ODS Moly Lanthana are applied is specialized furnace applications. The tensile properties of 1.0 and 0.5 mm sheets were evaluated with a “hot-grip” high temperature test system. The test temperature ranged from room temperature to above the recrystallization transition to a maximum of 1550C . The strain rate was varied from the ASTM E21 standard. The strength is more is more strain rate sensitive when the temperature is lower. The ODS Molybdenum-Lanthana sheet is mores strain rate sensitive that the pure molybdenum. Test specimen fracture surface was evaluated for understanding of related mechanism.
