    how are microstructures of alloys different when slowly cooled and precipitation hardened?

    Usually, a slowly cooled structure has a coarse microstructure - larger grains and larger/coarser precipitates. If one wants a fine microstructure and fine, dispersed precipitates, then one must quench below the transition temperature/threshold.

    Then one can anneal at a lower temperature.
