The influence of long maturing on stability of the alloy structure H20N80

摘要

By methods X-ray diffraction and electron backscatter diffraction have been investigated the long maturing effect on thestructural phase transformation in the alloy H20N80. After thermomechanical processing was obtained structure with high proportion special grain boundaries. It has been found that the average grain size decrease, changing the grain boundaries misorientation spectrum (Grain boundary character distribution-GBCD), changes in texture test the sample, the phase composition of the alloy to remain. The reasons for this behavior of the alloy be disscused.
