Abstract
In this study, the bonding of AISI 316L stainless steel and FeAl based intermetallic compound with friction welding was investigated. The FeAl intermetallic compound was produced in a vacuum arc melting furnace, while AISI 316L stainless steel was supplied from the market. The friction welding process was carried out at a friction speed of 1000 rpm, under a friction pressure of 150 MPa, for friction times of 6, 9 and 12 seconds. The strength of the welding interface was measured by shear test. The highest strength value was found to be as 281 MPa in the sample welded for 12 seconds. The hardness deviation in the welding zone was determined by micro hardness measurement from one material to another one. The welding interface was examined by Scanning Electron Microscopy (SEM) and the composition analysis along a line in the welding region showed that the amount of alloying elements changed. This revealed that the elements of both materials are diffused each other at the welding interface.
