The effect of fluidized bed heat treatment (FBHT) on low-carbon Mn-Si cast steel strength properties improvement,strictly ductility is shown in this paper.Fluidized bed heat treatment variants are chosen in order to eliminate the structure defaults after a crystallization process.FBHT parameters are set considering an initial state material chemical composition,structure morphology and application criterion after heat treatment.The results are verified according with the standard BS 3100:1991 recommendations.Fluidized bed heat treatment variants are chosen mainly in order to the Widmanst tten ferrite structures elimination,carbides morphology modification and matrix optimum performance properties achievement.The ZG35SiMn (EN:L30GS) FBHT processes results are verified by the metallographic researches,hardness/microhardness measurements and tensile strength examination.

Fluidized bed heat treatment variants are chosen in order to eliminate the structure defaults after a crystallization process. FBHT parameters are set considering an initial state material chemical composition, structure morphology and application criterion after heat treatment. The results are verified according to the standard BS 3100: 1991 recommendations. Fluidized bed heat treatment variants are chosen primarily in order to the Widmanst tten ferrite structures elimination, carbides morphology modification and matrix optimum performance properties.
