Özet
Ni3Al alloy was bonded with itself by friction welding. Various friction speeds, friction durations and friction pressures were tested to find optimum friction welding parameters, and the effects of the welding parameters on the welding interface, microstructure and mechanical properties were investigated. SEM and optical microscopy were carried out to examine the microstructural variations of the welding interfaces. Also, the microhardness distribution across the interface was evaluated considering the microstructural variations. In addition, the shear strengths of welded parts were measured. It was observed that the shear strengths of welds were dependent on welding time, friction pressure and friction speed. The maximum shear strength was found as 354 MPa.
