Transient Liquid Phase Bonding of T91 Steel Pipes Using Amorphous foil
T91 steel pipes were joined by Transient Liquid-phase bonding process using BNi2、Fe78Si9B13 and FeNiCrSiB amorphous filler in argon atmosphere. The microstructures and properties, as well as the element distribution of the T91 transient liquid-phase bonding joints with different filler metal have examined. The testing results showed that the tensile strength and bend strength at room temperature of the joint with FeNiCrSiB amorphous filler were equal to greater than that of the substrate. In contrast, however, Boride is found in the joint region bonded by with Fe78Si9B13 interlayer. TLP bonding using the nickel-base foil BNi2, resulted in a bond region stabilized by the high nickel concentration. It is considered that fracture of the joints is caused by these brittle intermetallics at interface and the discontinuity bond line microstructure.
