Metallographic and SEM microstructure examinations were used to determine the effects of shot peen, austenitizing time and temperature simultaneously. The results showed that with increasing austenitizing time and temperature of casting sample, carbides resolved in austenite phase and by further increase of austenitizing temperature and time, the austenite grain size becomes larger. Metallographic images illustrated that shot peening on Hadfield steel surface; Austenite - Martensite transformation has not occurred, but its matrix hardened through twining formation process. © Published under licence by IOP Publishing Ltd. publisher: Institute of Physics Publishing date: 2018 type: Conference or Workshop Item type: PeerReviewed identifier: Beheshti, M. and Zabihiazadboni, M. and Ismail, M.C. and Kakooei, S. and Shahrestani, S.
