## Description

- description: The effects of C and N on solid solution strengthening and grain refinement
    strengthening were quantitatively evaluated using various austenitic stainless
    steels in which C and N were added independently to Fe-18 mass%Cr-12 mass%Ni alloys.
    As a result of evaluating the amount of solid solution strengthening from the
    intercept value in the Hall-Petch relationship, it was confirmed that N has a
    stronger solid solution strengthening capacity than C. On the other hand, the
    addition of C and N increased the slope of the Hall-Petch relationship, the so-called
    Hall-Petch coefficient, and the amount of grain refinement strengthening increased.
    Comparing the effects of C and N, there was no significant difference in the effect
    of increasing the Hall-Petch coefficient between the two elements at the same
    amount of addition. The critical grain boundary shear stress measured by nanoindentation
    tests and the Hall-Petch coefficient corresponded well for both steels, demonstrating
    that the increase in critical shear stress due to the addition of C and N results
    in increased grain refinement strengthening. However, the amount of grain boundary
    segregation was calculated to be considerably higher for C than for N, suggesting
    that N is more effective than C in increasing the critical grain boundary shear
    stress.
