Abstract
- This paper presents an overview of bainite transformation in low carbon steel, which is alloyed with some alloying elements such as Mn, Si, Cr. The article also presents an overview of the transformation mechanism of this steel group. From the synthesis of research works, the influence of alloying elements on steel's microstructure and mechanical properties has been determined. And the final article, the bainite microstructure of CMnSi steel was found when deforming and heat treatment. By OM, the bainite structure was found. The article presents the influence of the deformation process on the microstructure and mechanical properties of low carbon alloy steel, which heat treatment by TBF processing. The samples are deformed at different levels: 20%, 40%, and 80%. The research results show that: When the sample was deformed with 80%, the highest strength was 800MPa, the highest elongation was 36%, the product between the strength and the elongation (R<subscript>m</subscript>*A) was the highest: 28774MPa*%. This alloy deformed at a level of 80%. The content of austenite in this alloy's microstructure was the highest, about 16%; the content of ferrite was 52%, with the average particle size of ferrite being 6.4 µm; the particle of residual austenite was 2 µm. The microstructure results have contributed to improving the mechanical properties of steel. The phase that improved the mechanical properties of this alloy had grain size and dispersed.
