Abstract
- Metallic reinforcing titanium is added to the magnesium matrix to improve the mechanical properties without losing ductility. Titanium has negligible solid solubility in magnesium below 500°C therefore it does not form a tertiary hard phase with Mg. Therefore, when titanium is added to magnesium, both strength and ductility are improved. However, due to the low solid solubility of Ti in Mg, the bonding between matrix and reinforcement is poor. Therefore, a small amount of metallic reinforcement Cu is added to fabricate Mg/Ti/Cu hybrid composites by powder metallurgy technique to enhance the bonding between Mg and Ti. Cu is selected as a binding agent because it has significant solid solubility with Ti and Mg. In the present work, the effect of Cu on the physical, mechanical, and thermal properties of Mg/Ti/Cu composites has been investigated. The addition of Cu was found to decrease the strength, hardness, and wear rate. On the other hand, the thermal conductivity increased. The strength, wear resistance and thermal stability of the prepared Mg- based hybrid composites are sufficient enough to replace some components of cast iron and aluminum in automotive special seat frames, door panels, brake disks of light-duty vehicles, etc. Thus, the prepared material is recommended for use in automotive and other industries.
