Effect of Ti De-oxidation on Solidification and Post-Solidification Microstructure in Low Carbon High Manganese Steel, Part-II Austenite Grain Growth and Ferrite precipitation

摘要

Particle pinning of austenite grain boundaries during grain growth is an important issue for refinement of microstructure. Heterogeneous nucleation of ferrite is important for micro-structure control during welding and heavy plate-steel manufacturing. In this work, the effect of de-oxidation particles on the austenite grain growth and ferrite precipitation were investigated following the previous report.
