Fabrication of Ingot with Lotus Type Through-Holes in Semisolid Condition

Abstract:

In this paper, an easy casting method of an ingot with through holes is shown. The Core-Bar-Pulling Method is proposed to improve the disadvantages of lotus type porous metal. The through holes were formed by pulling core-bars from a semisolid ingot. Holes with diameters ranging from 0.5 mm to 5 mm and length 50 mm were made in Al-Si alloy ingots. The relationship between temperature and formability of the holes was investigated by using eutectic Al-Si alloys. The pulling of core-bars and the forming of holes were easy, under the condition that the Si content was less than 6 mass%. This means that the forming of holes in Al-Si alloys is easy under the condition that flow ability at semisolid condition decreases.
