Abstract

Directionally solidified sample of Fe-C alloy in a vacuum Bridgman-type furnace was produced under an argon atmosphere. The pulling rate was v = 83.3, 125.0 and 166.7 μm/s (300, 450 and 600 mm/h) with constant temperature gradient G = 33.5 K/mm. The microstructure of the sample was examined on the longitudinal section using an optical microscope and scanning electron microscope. The average interphase spacing λ was measured on longitudinal section of the sample. The relationship between λ and v was determined using linear regression analysis.
