This study proposes a novel method for predicting material creep behavior based on the ZC parameter method using limited creep strain data, aiming to address the limitations of traditional creep prediction methods under conditions of high data variability and incomplete experimental data. A systematic prediction of the creep behavior of DZ125 alloy was conducted, analyzing the creep curves and rupture lifespans under varying temperature and stress conditions. The results indicate that the ZC parameter method can accurately predict complete creep curves from limited creep stress-time data, with predicted values closely aligning with experimental data; all predicted data points fall within the 95% confidence interval. Furthermore, the ZC parameter method covers a broader strain range with smaller errors in lifespan predictions, offering a reliable approach for forecasting the creep behavior of high-temperature alloy materials. The study provides new theoretical support and practical application references for the prediction of creep performance in materials.
