Analisis Pengaruh Temperatur Tuang pada Sifat Mekanik dan Karakteristik Mikrostruktur Connecting ROD Honda Revo Berbahan Al-Cu-Mg dengan Menggunakan Metode Sand Casting

Abstract

This study aims to analyze the effect of pouring temperature variations on the mechanical properties and microstructure of connecting rods made of Al-Cu-Mg, produced using the sand casting method. The process was conducted to improve the quality of casting results by varying the pouring temperature at 700°C, 750°C, and 800°C. Mechanical properties were tested through tensile, impact, bending, and hardness tests, while microstructural analysis was carried out using metallographic methods. The results showed that variations in pouring temperature significantly affected the mechanical properties and microstructure of the material. A pouring temperature of 750°C yielded the best mechanical properties with maximum tensile strength and optimal hardness, while 800°C tended to cause greater porosity in the microstructure. The material's microstructure also exhibited a significant influence of temperature variation on phase distribution and grain size. This research provides new insights into optimizing casting parameters to produce Al-Cu-Mg materials that are strong, corrosion-resistant, and lightweight, making them highly relevant for automotive applications.
