Solidification process, microstructure, and mechanical properties of Cr-doped high boron Fe-based alloy

High boron Fe-based alloys, possessing superior wear-resistant performance, have always been restricted to be applied in impacting conditions by the poor toughness. In the present work, Fe-3.0B-0.3C alloy has been toughened by introducing Cr element. The evolutions of the solidification process, microstructure and the mechanical properties have been systematically investigated by means of the scanning electron microscope (SEM), transmission...
