It is generally known that boron is an effective activator of the sintering process of iron as well as stainless steels. During sintering, boron contributes to the formation of a liquid phase wetting the surfaces of powder particles. As a consequence, a reduction of porosity, the rounding of pores and an increase in density is obtained. It is necessary to improve mechanical properties and corrosion resistance. The aim of this study is to investigate the effect of the addition of boron in the amounts of 0.2, 0.4 and 0.6% wt. on the density, microstructure and selected properties of sintered 17-4 PH stainless steel.
