| Abstract | ||
| The aim of this research is to study the ability of joining porous (Al-Si) alloy to solid Aluminum using Friction Stir Welding Method . The porous alloy is fabricate using casting method by adding(20,30,40) weight percent of Poly- athelin as space holder materials. The welding process is done using different welding speed (30,40and60)mm/min, with constant rotational speed (900) rpm. Microstructure evaluation showed that it is possible to weld porous alloy to aluminum in the solid state welding by friction stir process . Hardness test results showed that the welding zone hardness is higher than that of welded materials, and the weld zone hardness increased with increasing welding speed .The tensile test results showed that the bonding strength increased with increasing welding speed at constant space holder weight percentage, and it decreases with increasing addition percentage of space holder. | ||
