A Study of the Properties and Structure of Rolling-Mill Iron Modified with Boron

Resumo

The effect of boron additions on the properties and structure of rolling mill iron is studied. The composition of boride phase and carbides, and also the ratio of structural components in iron with different boron contents are determined. Structural transformations in iron during heat treatment are studied by differential thermal analysis and differential scanning calorimetry. The optimum concentration of boron in iron for improving its properties is determined.
