It enables heat input into the system to be controlled. In this study, Aluminum powders were compacted at 350,400 and 450 MPa pressure and sintered at 450 degrees C temperature for 30 minutes in Ar atmosphere. Sintered powder metal parts were joined to each other by FSW at the speed of 1800 rpm and traveling welding speed 200 mm/min under a constant friction force. The results show that the amount of porosity affects the welclability of powder metallurgy (P/M) parts. Furthermore, the porosity and microstructural evolution of the Aluminum also affected the hardness values of the tested materials.eninfo:eu-repo/semantics/closedAccessFriction stir weldingAluminiumPowder metallurgyPorosityConference Object10.4028/www.scientific.net/MSF.534-536.789534-5367897922-s2.0-38549161114Q4WOS:000244522400197N/A
