A torsion pendulum device is described for measuring the amplitude‐dependent damping properties of high‐temperature alloys both at room temperature and at elevated temperatures. Its features include the use of data processing techniques for rapid access to damping information and the use of a simple specimen geometry to allow specimens to be cut from bulk engineering samples. Some typical results obtained with the system are given to illustrate its capabilities and the extraneous background losses in the machine are discussed.
