    Effect of regular thicknesses on the microstructural and quantitative analysis for a hypo-eutectic ductile iron alloyed with Ni and V by Colin-García E., Sánchez-Alvarado R.G., Cruz-Ramírez A., Suarez-Rosales M.A., Portuguez-Pardo L., Jiménez-Lugos J.C.

    Published 2024-01-01
    “…The low content of vanadium added to the ductile cast iron had a negligible effect on the solidification pattern, which was mainly due to the graphitizing impact of the nickel and silicon addition. The results of the microstructural characteristics are therefore primarily due to the cooling rate, which is determined by the casting thickness. …”
