Evaluation of Vickers Hardness Number of Al-Si Alloy Under Heat Treated Conditions
International Journal of Engineering and Advanced Technology, 2021 The paper deal with the hardness property assessment of various Al-Si alloys under heat treated conditions. The tested specimens have the compositions of Si with percentages such as 12 18 and 24. The fabrication of the selected composition is carried out by melting the material to the melting temperature of around 800°C.
