摘要： Disclosed herein are systems, devices and methods for creep testing selected materials within a high-temperature molten salt environment. Exemplary creep testing systems include a load train for holding a test specimen under a load within a heated inert gas vessel. An extensometry system can be included to measure elongation of the test specimen while under load. The extensometry system can include fixed members and axially translating member that move along with the elongation of the test specimen, and the system can include a sensor to measure the relative axial motion between such components to measure elongation of the test specimen over time. The test specimen can include a cylindrical gage portion having an internal void filled with a molten salt during creep testing to simulate the corrosive effect of the molten salt on the specimen material during testing.

摘要： A test rig combining high-frequency tribological stress and low-cycle fatigue. The test rig includes a first test piece which is fixed to a frame and defines at least one bearing surface, a second test piece which is connected to an actuator for loading the second test piece so that it bears against the at least one bearing surface of the first test piece, a heater configured for heating the test pieces and a vibration generator, such as a shaker, for loading the test pieces in a vibratory manner so as to carry out a fretting fatigue and low-cycle and high-cycle fatigue test. One of the test pieces includes a portion in the shape of a turbine engine rotor blade root and which is inserted in a groove having a shape that is substantially complementary to the other test piece so as to reproduce a turbine engine blade-disc attachment.

摘要： A heating system for use in mechanical testing at scales of microns or less includes a stage heater. The stage heater having a stage plane, and a stage heating element distributed across the stage plane. Two or more support mounts are on opposed sides of the stage plane. A first bridge extends from the stage plane to a first mount of the two or more support mounts, and a second bridge extends from the stage plane to a second mount of the two or more support mounts. The first and second bridges provide a plurality of supports between the stage plane and two or more support mounts to accordingly support the stage plane. In another example, the heating system includes a probe heater configured to heat a probe as part of mechanical testing.
