title = "Material damping test of high temperature alloy",
abstract = "This study presented a high temperature material damping test method and developed an experiment apparatus. A resonance dwell technique using a double-reed specimen was proposed to test the material damping of high temperature alloy. This test system consists of five subsystems including heating oven and heating control system, vacuum control system, temperature monitoring system, water cooling system and vibration signal measurement system. Using this testing system, the material damping of Ti-6-4 alloy was tested, and the relations between material damping and temperature or frequency were obtained. Test results shows that Ti-6-4 damping increases with temperature, but it is very nonlinear dependence; Ti-6-4 damping ratio keeps nearly constant from room temperature to 600 F° , and then rapidly increase at higher temps above 600 F°; very slight dependence of damping for Ti-6-4 on frequency was observed.",
