Penambahan sr pada aluminium paduan a356 dengan metode lost foam casting (lfc)
نویسندگان
چکیده
The casting process and cooling rate determine the morphology of authentic silicon particles produced in aluminum alloys. slow alloy through Lost Foam Casting (LFC) method a result low mechanical properties. purpose this study was effect added Strontium (Sr) modifier to A356 on microstructure properties LFC method. Aluminum alloys are melted using crucible poured at temperature 730 oC surface polystyrene pattern which has been coated with refractory materials. addition studied for its changes (hardness, impact strength, tensile strength). results indicate change from an acicular filamentous form. value hardness, maximum strength castings increased after Sr A356.

The Effects of Gating Systems on the Soundness of Lost Foam Casting (LFC) Process of Al-Si Alloy (A.413.0)
The effects of gating systems, number of runner, and their locations, in the Lost Foam Casting (LFC) of Aluminum alloy (A.413.0) were investigated. Six different gating systems, with one or two running systems were designed. X-ray radiography and the three axis-bending tests have been employed to evaluate the casting soundness and quality. The results revealed that gating systems have a major e...

متن کاملBehavior of Generated Gas in Lost Foam Casting
In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...
