PRODUCTION METHOD FOR ALLOY 690 ORDERED ALLOY OF IMPROVED THERMAL CONDUCTIVITY, AND ALLOY 690 ORDERED ALLOY PRODUCED THEREBY

摘要

The present invention relates to ordered Alloy 690 with improved thermal conductivity. By maintaining Alloy 690 in a temperature range of 350-570 °C for a proper amount of time, the atomic arrangement is controlled to properly form the ordered phases. The ordered phases formed in the ordered Alloy 690 increases its thermal conductivity due to a low thermal scattering effect of the ordered phase as observed in pure metals.
