Abstract

PURPOSE:To obtain the testing device by which fatigue characteristics of configuration memorizing alloy are obtained, by imparting a constant load or constant displacement to a test piece comprising the configuration memorizing alloy, and repeatedly applying the heat cylces of heating and cooling to said test piece. CONSTITUTION:When a weight 14 which gives the constant load is connected to the test piece 2 which is subjected to the configuration memorizing process under the compressed state, the test piece 2 is pulled and deformed. Then a current is supplied to the test piece 2 from a power source 15. The test piece 2 is heated, contracted, and deformed by the configuration memorizing effect. Then a temperature regulator 19 is actuated by the output of a temperature detector 18, and a switch 16 is actuated and switched. As a result, power supply to the test piece 2 is stopped, a refrigerant injector 21 is actuated, the test piece 2 is forcibly cooled and undergoes tensile deformation. By repeating this procedure, the fatigue characteristics such as loads, displacements, number of repeating loads, and the like in the heat cycles are measured, and the characteristics are obtained.
