The nature of hardening and embrittlement of steel 0Kh20N9S2BGTYu

Conclusions

  1. 1.

    Stell 0Kh20N9S2BGTYu has two temperature ranges of embrittlement \t-450–650\dgC and 700–850\dgC. In the high-temperature range \gs phase is formed.

    In the low-temperature range there is precipitation hardening of the ferritic component. At 500–550°C holding for 5 min results in substantial hardening and a reduction of plasticity, and therefore the temperature of the molten alkali used in pickling should not exceed 420°C.

  2. 2.

    The electron microscopic examination of the samples tempered in the embrittling low-temperature range showed precipitates of intermetallic phase with an ordered cubic structure coinciding crystallographically with the lattice of the matrix (\ga solid solution) but with a lattice parameter (5.7 \0A) double that of the matrix.
