RODRIGUEZ GALEANO, Karol Felipe. Influence of Boron in the mechanical properties of Bainitic steels. Iteckne [online]. 2013, vol.10, n.1, pp.128-136. ISSN 1692-1798.

In the last decades there have been important developments in industrial equipment of heating and cooling such as are furnaces, muffles, among others, making them very stable and allowing to make temperature increases and decreases in a controlled and precise way; which is why they studies about parameters needed to acquire special materials have allowed, by combined thermal and mechanical processes such as the bainitic steels. Today it continues to research this type of steel, changing alloys percentages and watching how they can make mechanical properties vary, thus allowing to characterize and provide a strong basis for industries using new materials that have less manufacturing processes, and being more economical and less hostile to the environment. In this article bainite microstructure is characterized and takes into account the changes of properties that are of great industrial importance regarding the change of the amount of boron present, some of these properties are the yield stress, ultimate stress to stress, the engineering strain when these materials are subjected to strain and a comparison with pearlitic steels, which represent a significant part of industrial applications for steel.

Keywords : bainitic steels; boron; mechanical properties.
