	abstract = {The distribution of metals in the intracluster medium (ICM) of galaxy 
clusters provides valuable information on their formation and evolution,
on the connection with the cosmic star formation and on the effects of
different gas processes. By analyzing a sample of simulated galaxy
clusters, we study the chemical enrichment of the ICM, its evolution,
and its relation with the physical processes included in the simulation
and with the thermal properties of the core. These simulations,
consisting of re-simulations of 29 Lagrangian regions performed with an
upgraded version of the SPH GADGET-3 code, have been run including two
different sets of baryonic physics: one accounts for radiative cooling,
star formation, metal enrichment and supernova (SN) feedback, and the
other one further includes the effects of feedback from active galactic
nuclei (AGN). In agreement with observations, we find an
anti-correlation between entropy and metallicity in cluster cores, and
similar radial distributions of heavy-element abundances and abundance
ratios out to large cluster-centric distances ({\textasciitilde}R180). In the outskirts,
namely outside of {\textasciitilde}0.2R180, we find a remarkably homogeneous metallicity
distribution, with almost flat profiles of the elements produced by
either SNIa or SNII. We investigated the origin of this phenomenon and
discovered that it is due to the widespread displacement of metal-rich
gas by early (z{\textgreater}2-3) AGN powerful bursts, acting on small
high-redshift haloes. Our results also indicate that the intrinsic
metallicity of the hot gas for this sample is on average consistent with
no evolution between z=2 and z=0, across the entire radial range.},
