Abstract Scope |
Resistance to creep deformation is an important characteristic for high-temperature load bearing applications. This work evaluated bending stress state in sheet material for creep testing. These test methods were applied as a screening test for evaluating the creep resistance of sheet molybdenum and Mo alloys against various thermal process conditions. These methodologies could be expanded for evaluating other high-temperature alloys for creep screening tests. Molybdenum is applied in high-temperature application because the retention of strength and elastic modulus in material processing applications. The first stage of the testing is used for evaluating creep resistance of commercial Mo & Mo alloys for application in high-temperature furnaces capabilities. Testing includes cantilever and 3-point bend creep tests for both arc-cast and powder metallurgy Mo at various temperature regimes. Results of the creep tests will show the optimum thermal condition for resistance at different temperature regimes. |
