The creep of steel at high temperatures
WebMuch the most important temperature range, however, is the band of high temperatures between 0.3 and 0.9Th1, where qI is the melting point of the basic metal. The creep occurring below and above this band is of less importance. In our river it occupies only a narrow channel which runs dry in some years. 2.1. WebThese physical studies have shown that there are several different creep régimes depending mainly on the temperature. If TM is the melting point of the metal in question, the different régimes roughly cover the temperature ranges 0-0·3 …
