The response characteristics of mechanical-quenching (MQ) are discussed and the influencing factors on MQ measurement such as the loading stress, loading rates and loading cycles are analyzed. Moreover, as an evaluation factor, the lifetime is introduced to measure the MQ change, which is proportional to the applied load and is inversely proportional to the loading rate. While the MQ measurement during the multiple loading cycles, the decay lifetime kept stable, indicating that the lifetime can be used for quantitative nondestructive evaluation especially for the multiple loading cycles.
