The effects of titanium and zirconium additions on the non-metallic inclusions and microstructure of PK942 (X11CrNiMo12) steel were investigated. Laboratory steel charges with additions of Ti, Zr and a combination of both elements were melted. The inclusions’ size, quantity, distribution and composition were analysed using optical and scanning electron microscopy (SEM). Other than the difference in -ferrite quantity, there are no significant differences in the microstructure. The Ti and Zr additions had a significant effect on the non-metallic inclusions, and while the addition of Ti did have an effect on the composition of inclusions, the addition of Zr also had a great effect on the size distribution and the number of non-metallic inclusions. The result of the Zr addition was a large reduction in the total non-metallic inclusion surface area. The additions of both titanium and zirconium had similar effects to the addition of Zr. Thermodynamic reactions were considered to explain the modification of the non-metallic inclusions.
