Abstract
EH36 shipbuilding steels with varied Ti contents have been designed to investigate the roles of Ti upon inclusion evolution and microstructural characteristics. As the Ti content increases, the number density of Ti-containing inclusions appreciably multiplies, and corresponding area fraction of acicular ferrite boosts sharply from 5.0 to 29.9 pct. Additionally, through in-situ confocal scanning laser microscopy, it is clarified that acicular ferrite start temperature has been elevated, thanks to the population of Ti-containing inclusions.
