Maps of intragranular precipitation strengthening

Maps of strengthening by small (semi)coherent precipitates homogeneously dispersed in the grains have been constructed. They can show the most probable dislocation-particle interaction mechanism and the strengthening effect of a given dispersion of particles. As an application, the effect of-Ni₃(Al, Ti) and M₂₃C₆ precipitation in austenitic steels is discussed.
