Abstract

The aim of this study is to investigate the corrosion susceptibility and
microstructural evolution of austempered AISI 1030 steel in seawater
environment. The steel samples were austempered at varied
temperatures of 300˚C, 320˚C and 340˚C respectively. The corrosion
behaviour was determined by means of optical metallography
microscopy (OMM) and weight loss measurement (WLM) at an interval
of 15 days for the period of 75 days. Results indicated that, the
specimens’ austempered at 320°C offered fine microstructure due to the
presence of acicular bainite and also some martensite in the
microstructure. Austempering at 300˚C and 320˚C yielded a carbide-free
bainite microstructure. Therefore, on the corrosion rate, the results
indicated that the sample austempered at 320˚C was relatively the most
corrosion resistant, followed by sample austempered 300˚C and lastly
sample austempered at 340˚C.
