Analysis of Boride Phase Composition in High Boron Alloyed Stainless Steel Containing Titanium

Abstract:

Hard and brittle (Fe,Cr)₂B phase caused by excess boron in high boron alloyed stainless steel has adverse effects on the hot working performance and mechanical properties of material. Adding Ti into high boron alloyed stainless steel can improve the type, morphology and distribution of boride phase. The results show that TiB₂ phase with petals or small block shape forms after adding Ti into high boron alloyed stainless steel, and as the increase of Ti content, TiB₂phase replaces (Fe, Cr)₂B gradually. Moreover, the petal-like TiB₂ phase becomes smaller and more granular after high temperature deformation, and the segregation of matrix composition is significantly weakened by the formation of TiB₂ phase.
