More about the book
The aim of the work was to provide a basis for the development of B-alloyed tool steels. To this end, the effect of the elements B and Cr on the microstructure formation, the stability and the micromechanical properties of hard phases in hypoeutectic Fe-C-B and Fe-C-B-Cr alloys was analyzed. Additionally, interactions of the elements B and Cr with Mn, Mo, V or Nb were investigated. Laboratory alloys of the systems Fe-C-B and Fe-C-B-Cr with additions of the elements Mn, Mo, V or Nb were casted and characterized experimentally. Based on these results, two B-alloyed cold-work steels (CWS) were developed and processed by means of melt and powder metallurgical manufacturing. The novel B-alloyed CWS achieve the same or higher toughness, strength and wear resistance compared to conventional CWS of the Fe-Cr-C and Fe-Cr-V-C systems, while material cost for the B-alloyed CWS are significantly lower.
