The creep curves of superalloys as conventional high temperature materials consist of three regions which are
transient creep, steady state creep and accelerating creep. However, unlike this, it was reported that anomalous
strengthening phenomena appeared in the creep of the superalloy in high temperature and low stress regions, and creep curves repeating unique unevenness were drawn. Although no single equation representing such anomalous creep curves has been found so far, we succeeded in expressing the above-mentioned anomalous creep curves with single equation using discrete cosine transform. Therefore we report the above in this paper.
