논문 초록 (Abstract)

The lost foam casting method was used to fabricate Al-Si alloy thin sheet specimens; the effects of chemical composition and process variables on the mold filling and mechanical properties were investigated. The mold filling capability was observed to be proportional to the pouring temperature, and both the vibration imposed during the casting and the application of a pattern coating had rather negative effects. The mold filling capability also decreased with the addition of Mg or TiB. When the Mg content increased, the tensile strength of the cast alloy was enhanced, but the elongation decreased. However, after T6 heat treatment, both the strength and the elongation were improved. TiB addition for grain refining or pattern coating did not significantly affect the tensile properties.
