Effects of brazing parameters on the vacuum joint strength and hardness of Inconel Superalloy
The effect of different brazing clearances and temperature has been investigated on Inconel Superalloy vacuum brazing.The brazing clearance and temperature are crucial to the joints brazed in the Inconel Superalloy brazing by using Nickel based filler.The high temperature tensile strength and microhardness are evaluated at different brazing parameters.The results show that fracture occurs wholly within the braze metal.Deformation appears to be confined to the braze metal with the base metal,showing very little plastic deformation.It is shown that the brazing time plays an important role in the brazing process.The peak of microhardness is at the centerline of braze region.Induction heating has little effect on the base materials.
