GRAIN BOUNDARY FEATURES AND CREEP BEHAVIOR OF Fe-15Cr-25Ni ALLOYS
Fe-15Cr-25Ni合金晶界特征与蠕变行为

Creep behavior of Fe-15Cr-25Ni alloys with different grain boundaryfeatures has been investigated. The single-phase alloy exhibits typical recovery creepcharacter, and for the alloy with M_(23) C_6 precipituted at grain boundaries, the creeprate largely decreases and the creep behavior is also different from the former.Creep mechanisms for two grain boundary features have also been discussed.
