Its quite simple. Answer is solute drag effect. Solute or impurity atoms segregates to the grain boundaries so grain boundary movement disturbs so rate of new grain formation decreases. Or rate of recrystallization decreases.

Solute atoms, both deliberate additions and impurities, have a profound influence on the recrystallization kinetics. Even minor concentrations may have a substantial influence e.g. 0.004% Fe increases the recrystallization temperature by around 100 °C (Humphreys and Hatherly 2004). It is currently unknown whether this effect is primarily due to the retardation of nucleation or the reduction in the mobility of grain boundaries i.e. growth.
