The coherency between the parent phase and particle is much better in precipitation-hardened alloys compared to dispersion hardened alloys.

The coherency between the parent phase and particle is much better in precipitation-hardened alloys compared to dispersion hardened alloys. Correct Answer True

The second phase particle in the precipitation-hardened system come out of matrix only, so there is atomic matching between planes, and define the relationship between orientation. But in dispersion hardening, it is like mechanical mixing, so not coherency between matrix and particles.
