The effect of high boron additions on the microstructure of cast steel

Öz:

This study summarizes research into the effect of high boron additions on themicrostructure of cast steel under the certain carbon (0.42 C wt.%) and chromium(11.65 Cr wt.%) content. Varying amounts of boron between 0.48 - 4.75 wt.% wasadded into steel melt. The boron analysis of the alloys was conducted by wetchemical analysis. The microstructure of the specimens was characterized withoptical microscope, Scanning Electron Microscope with Energy Dispersive X-RayAnalysis (SEM/EDX) and X-Ray Diffraction (X-RD). The experimental resultsshowed that high boron steel was successfully produced by sand casting withhigh casting yield. The microstructure of boron alloyed high chromium cast steelconsists of three dimensional networks of M2B borides surrounding the martensiticmatrix in as cast condition. Under the certain carbon and chromium content,boron carbide volume fraction is directly depended on the boron additions. Dueto the high amount of chromium and boron, carbides and borides were embeddedin each other in all additions. In the specimens having less than 2.44 B wt.%,carbide/boride structure was fishbone type with dendritic distribution over thematrix whereas rod/needle like structure with randomly distribute was observedin specimens having 2.44 - 4.75 B wt.%. In all specimens containing boron, M2Band M7(C, B)5 type carbides/boride peaks were detected by X-RD analysis.
