Abstract
Nonequilibrium segregation of manganese at grain boundaries of high-manganese austenitic steels, which was reported previously, was verified by AES and TEM—EDS analysis in this study. The deformation behavior of high-manganese steels with different manganese content was characterized, and the low-temperature toughness for various heat-treatment conditions was determined. On the basis of these data, the fracture mechanisms are discussed. The “hard-shell” model of low-temperature fracture of high-manganese steels, which was proposed by Xue in the earlier paper, was validated by the ultra-microhardness test.
