Incoloy Alloy (I800) has been proposed for use in the receiver tube panel arrays in a number of advanced solar central receiver concepts. The effects of deformation on corrosion resistance in sodium nitrate and potassium nitrate salt mixtures have been tested in constant load tension creep at elevated temperatures (550/degree/C/less than equivalent to/T/less than equivalent to/670/degree/C). Depending on the temperature and initial stress, fracture times ranged between 300 and 1000 h. Metallographic observations revealed severe surface oxidation. 12 refs.
