Abstract
Tensile properties of DU-10Mo at room temperature through approximately 400â¯Â°C determined from the tests conducted herein suggest the material is stronger and has lower ductility than what has been reported previously in the literature. The explanation for these differences has yet to be determined, but is likely related to differences in grain size and/or impurity content, and variation in fabrication history. At the highest temperatures tested (550â¯Â°C) better agreement between the values reported here and available literature was found. As expected, yield and ultimate tensile strength decreased with increasing test temperature. Generally, the yield stress for all foil processing conditions was found to be in the range of 1100â¯MPa for room temperature tests, and in the range of 200â¯MPa for tests conducted at 550â¯Â°C. Ultimate tensile stress was in the range of 1175â¯MPaâ¯at room temperature, decreasing to approximately 225â¯MPaâ¯at 550â¯Â°C. Elongation increased significantly, from 0 to 2% at room temperature to 50% or more for the tests at 550â¯Â°C.
