Local Mechanical Properties of Borides in Fe-B Steels

Abstract:

One of the ways to increase service life of the abrasive wear parts are new developed as-cast steels with ceramic phase. Expensive wear resistant high chromium cast iron can be exchanged by Fe – B alloys. The mechanical properties of the borides in the Fe – B cast iron depend on alloying elements like chromium or nickel. A set of sample with different content of carbon, chromium, nickel and boron has been prepared. Chemical composition (GDOES) and microstructure of the as-cast alloys have been investigated as well as the hardness and Young modulus of the borides. Our results shown that mechanical properties of borides depends both on chromium and carbon content.
