We carried out detailed abundance analysis of two A-type stars; π Dra and HR 7545. High resolution echelle spectra of these stars were obtained at the TÜBİTAK National Observatory. We determined the fundamental parameters of each target star using traditional methods. We also plotted the stars on the H-R diagram and calculated the masses from evolutionary tracks and ages from isochrones.
