Abstract

In the world of the metal casting industry, we often hear about a type of cast iron called white cast iron. White cast iron is a type of cast iron that does not have graphite so it has mechanical properties that are very hard but brittle. This research aims to determine the effect of normalizing at a temperature of 850°C with a holding time of 20 minutes on the microstructure, phase chemical composition, and hardness value of white cast iron. Metallographic testing and composition testing were carried out using Scanning Electron Microscope – Energy Dispersive X-Ray Spectroscopy (SEM-EDS), while hardness testing was carried out using the Vickers method. The results of SEM-EDS testing show that white cast iron that has undergone an normalizing process contains graphite, cementite (Fe3C) and pearlite phases. In the graphite phase there are Carbon (C) elements of 80.30% by weight, Ferro (Fe) by 16.10% by weight, and Oxygen (O) by 3,6% by weight. Then in the cementite phase (Fe3C) there are Ferro elements (Fe) amounting to 93.506% by weight, Carbon (C) by 6.394% by weight, and Oxygen (O) by 0.100% by weight. And in the pearlite phase there are Ferro (Fe) elements of 93.500% by weight, Silicon (Si) by 1.400%, Carbon (C) by 3.90% by weight, and Oxygen (O) element is 1.200% by weight. The results of hardness testing show that the highest hardness value occurs in raw material with an average hardness value of 527,033 VHN. Meanwhile, the lowest hardness value occurred in test specimens that had been normalizing with an average hardness value of 444,933 VHN.
