1 Characterization of TiB2 reinforced aluminum matrix composite synthesized by in situ stir casting method https://jourcc.com/index.php/jourcc/article/view/jcc241 10.29252/jcc.2.4.1 20.1001.1.26765837.2020.2.5.1.5 1 In this study, TiB2 reinforced Al-matrix composite was fabricated by in situ stir casting route, and the effect of processing parameters was investigated. X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) equipped with energy-dispersive X-ray spectroscopy (EDX) were used to study the composition and microstructure of the samples. Finally, to investigate the tribological and electrochemical behavior of the samples, wear tests (pin-on-disk) and potentiodynamic polarization tests (PDP) were used, respectively. Results showed that by increasing stirring time, both tribological and mechanical behavior of the samples improved. Also, it was found that by increasing the stirring speed of the melt to 180 rpm, the mechanical and tribological behavior of the samples improved, and by further increasing the stirring speed to 300 rpm, they were decreased. Consequently, samples containing lower than 7 wt. % TiB2 showed better metallurgical properties, due to lack of agglomeration. 163 170 Fereshteh Barragh Jam University of Maragheh Iran info@jurcc.com Hadi Bangi Houri Ferdowsi University of Mashhad Iran Pers73hadi@gmail.com Morteza Ferdosi Semnan University Iran info@jourcc.com In-situ Composite TiB2 Wear resistance Stir casting Article1.pdf [1] A.M.
