Influence of Ti addition on the microstructure and hardness properties of near-eutectic Al-Si alloys

In this study, the influence of Ti addition on the microstructure and hardness of near-eutectic Al-Si has been investigated. Near-eutectic Al-Si alloys (13.1 wt. % Si) with 0.1, 1, 2, 3, 5, and 10% Ti have been utilized for this purpose. The melting operation was carried out in an electrical furnace, where the charge materials were placed in a graphite crucible. After melting, alloys have been cast in the metal mold at 1100 degrees C and solidified. (c) 2006 Elsevier B.V. All rights reserved.
