Fabrication of Lotus Type Porous Ingots Using the Core-Bar Pulling Method

Abstract:

The application of the core-bar pulling method to Al-Mg, Al-Mn, Al-Cu and Cu-Zn alloys was investigated, using a stainless steel core-bar with a 2 mm diameter to produce through-holes in 50 mm long ingots. This study confirmed that through-holes could be produced in these alloys in this manner. The results demonstrate that the temperature ranges over which the core-bar can be extracted are quite wide, so precise control of the ingot temperature is not required when producing through-holes. The core-bar pulling method is evidently a facile means of fabricating through-hole lotus type porous metals.
