We use IllustrisTNG simulations to investigate the mass-metallicity relation (MZR) evolution of star-forming cluster galaxies as a function of the formation history of galaxy clusters. The simulations predict enhancement in the gas-phase metallicities of star-forming cluster galaxies (10^9<M_*<10^10 M_sun) at z<1.0 compared to field galaxies, consistent with observations. We find that the metallicity enhancement of cluster galaxies appears prior to their infall into the central cluster…
