Microstructural analysis of EN-GJS-450-10 ductile cast iron via vibrational casting
EN-GJS-450-10 ductile cast iron was produced with and without vibration to evaluate microstructural features. To investigate the effect of vibration, a reference, and two different castings having amplitudes of 0.9 mm and 1.8 mm were cast with a fixed vibration frequency of 50 Hz. The nodule count...

| description | EN-GJS-450-10 ductile cast iron was produced with and without vibration to evaluate
microstructural features. To investigate the effect of vibration, a reference, and two different castings having
amplitudes of 0.9 mm and 1.8 mm were cast with a fixed vibration frequency of 50 Hz. The nodule count
(density), form (type), size distribution, nodularity, and the fraction of graphite, percentages of both ferrite
and pearlite phases, length of ferrite shell, and pore, were evaluated via optical microscopy using an image
analysis software. It is observed that the microstructure of the cast iron is more uniform by vibrational casting
than that by non-vibrational casting. Additionally, mechanical vibration enhances nodule count and nodularity,
also, more ferritic matrix could be obtained after the application of vibration. Nodule count and nodularity of
vibrational casting with 1.8 mm amplitude increased from 226 nodule per mm2 and 80% to 311 nodule per mm2 and
86.5% of non-vibrational casting. Percentages of ferrite and graphite area dramatically improved from 24% and
16.5% for non-vibrational casting to 57% and 22.3% for vibrational casting with 1.8 mm amplitude, whereas the
percentages of pearlite and pores decreased significantly from 56.1% and 5% to 20% and 1%, respectively. |
