Characteristics Of Aluminium ADC 12/SiC Composite with the Addition of TiB and Sr Modifier
The addition of silicon carbide (SiC) as a reinforce in a composite can improve mechanical properties. In this study aluminium ADC 12 (Al-Si-Aluminium Alloy) is treated with an addition of SiC varied from (1; 1.5; 2; 2.5 to 3) vf% and mixed with 0.18 wt% Sr to change the morphology of the silicone e...
