Properties of pressurized lost foam casting of al-11si alloy
The paper presents the result of investigation on aluminum-silicon (LM6) alloy cast using pressurized lost foam casting process. The study investigated the effect of pressure and sand size on hardness and roughness of the casting produced. Air pressure of 1, 2, 3 and 4 bars was applied on the solidi...
