Gray cast iron has graphite flakes which makes it relatively weak and brittle. The addition of magnesium to gray cast iron resulted in nodular cast iron which has spherical graphite. The aim of this research was to investigate the changes in the microstructure and strength due to the addition of magnesium to gray cast iron. Microstructure observations were made by metallographic testing using Scanning Electron Microscopy and Energy Dispersive Spectroscopy. Tensile testing was carried out to measure the yield strength, tensile strength, and modulus of elasticity. The addition of magnesium to gray cast iron was observed to increase the yield strength by 179%, tensile strength by 238%, and decrease the modulus of elasticity by 94%.

“…The elements that are often alloyed into gray cast iron to improve their properties are manganese [8], sulfur [9], niobium [10][11][12], copper [13], molybdenum [14], silicon [15], and chromium [16]. Improved properties are also carried out by modifying the phase through processes such as quenching-tempering [17], austempering [18], spheroidizing [19], laser surface treatment [20], and flame hardening [21]. Changing the shape of sharp flake graphite into spherical graphite will reduce the stress concentration so that the cast iron becomes stronger and harder.…”

The addition of magnesium alloy elements followed by a flame-hardening process will change the phase configuration in gray cast iron. This study aims to investigate changes in microstructure and hardness due to these two processes. The addition of magnesium is conducted by adding FeSiMg as a carrier for magnesium. Metallographic examination to observe changes in microstructure was carried out using a Scanning Electron Microscope (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS). The formed phase is examined by X-Ray Diffraction testing. The hardness test was carried out using the Vickers technique on the surface of the gray cast iron, the nodular cast iron, and the flame-hardened nodular cast iron. Whilst for flame-hardened nodular cast iron, the Vickers technique was also conducted on a cross-section. The addition of the FeSiMg compound changed flake graphite into spherical graphite with increased hardness from 130 VHN to 313.22 VHN. The flame-hardening process in nodular cast iron results in the formation of a martensite phase and the disappearance of graphite on the surface of the material. The hardness on the surface of the material due to the flame-hardening process increased by 82.4% compared to the substrate.
