Fabrication of Open-Channel Aluminum by Template-Extraction Technique

Fabrication of Aluminum Alloy with Open-Channel and Columnar Structures through a Ceramic Fiber Template Method

“…Furthermore, the addition of MgH2 to boron nitride decreases the extraction force, as depicted by the lower curve in Figure 14b. It was shown that the decrease in the extraction force is attributed to the formation of porous layers between the template's stainless steel wires and the aluminum alloy [31]. Furthermore, Figure 15a,b shows the dependence of the extraction force of SUS template wires on the template length and the diameter, respectively.…”

“…Figure 1a shows a schematic drawing of the extraction procedure by gripping the whole jig and the aluminum ingot, and Figure 1b shows a photo of the extraction process using a tensile test machine. According to a previous investigation [31], it is known that the extraction force (tensile force) of n wires amounts to n times the extraction force per one wire. If n is a large number, a large extraction force should be necessary, so a large-capacity tensile test machine must be used, which affects the manufacturing cost, resulting in high cost performance.…”
