Özet
Powder metallurgy is one of the most common methods for fabricating many engineering components. However, one of the major difficulties for these materials is joining techniques. In this study, Aluminium powders produced by atomization method have been pressed with the pressure 370 MPa. They have been sintered under argon atmosphere in periods of 60 minutes at 600 °C afterwards. The dimension of Al plates were 5×45×55mm. Three tool rotation speeds (700, 900, 1100 and 1400rpm) in the clockwise direction were chosen and specimens were joined by friction stir welding (FSW) technique. The hardness values of welded specimens were evaluated and three point bending tests were performed. Also macro and microstructures were investigated for the tested materials. The optimum welding properties were obtained with 900 rpm tool rotation speed.© 2008 Metal Powder Industries Federation.
