Effect of Alloying Elements on the Structural Phase State of Hadfield Steel

Zhilkashinova, Almira / Skakov, Mazhyn / Abilev, Madi / Yerbolatuly, Dossym

This study examined the changes in the microstructure and phase composition of Hadfield steel depending on the content of the main elements Mn and C and the alloying elements Cr and V. Phase composition and fine structure of manganese steels were studied using X-ray diffraction analysis and electron diffraction using transmission electron microscopy. Samples of steel were undoped and were alloyed with Cr and V at a content of $\sim 0.4 %$ and $\sim 1 %$ by weight C and 6%–18% by weight Mn. The main phase of the steels, regardless of the Mn content, remained completely austenitic, and the introduction of Cr and V led to the expansion of the $γ$ region. The average scalar density depended on the concentration of Mn, whereas Cr and V shifted the region of the $ε$ phase toward a lower concentration of Mn and increased the content of the $α$ phase.
