<p>Gray iron has been a conventional material for automotive brake discs due to its thermal conductivity and low production cost. Achieving optimal wear resistance is crucial for ensuring performance and durability in this application. This investigation focused on the effect of titanium on the microstructure, mechanical properties and wear characteristics of gray iron. Various amounts of Ti ranging from 0 to 0.349 % were introduced into hypereutectic gray irons. The microstructures of the samples were examined using the optical microscopy (OM) and scanning electron microscopy (SEM) showing that the matrix structure consists of ferrite and pearlite along with lamellar graphite. Ti addition decreased the percentage of pearlite in the matrix significantly. In addition, Ti significantly refines graphite resulting in the Type-D gray iron microstructure. Energy Dispersive X-ray spectroscopy (EDS) revealed that TiC is the predominant Titanium-containing compounds (TCCs) in this study. TiC particles were dispersed and resided in the interdendritic area. The number of TiC increased with Ti added to the melts. Furthermore, the addition of 0.132%Ti resulted in the lowest specific wear rate at 3.16 × 10⁻⁵ mm³/Nm. This improvement in wear resistance was due to a combination of matrix structure and a reduction in the coefficient of friction. Additionally, Ti significantly increased the tensile strength by refining graphite and increasing primary austenite. However, the higher level of Ti did not show further improvements in both tensile strength and wear properties. Cooling curve analysis showed that Ti has an effect of lowering the eutectic temperature resulting in finer graphite.</p>
