Research on the Limiting Inner Pressure of Metallurgical Composite Bimetallic

Abstract:

The metallurgical composite bimetallic tube, Incoloy825/X60, has been manufactured by a novel centrifugal casting plus extrusion compound technique. Based on the Incoloy825/X60 bimetallic tube, the limiting inner pressure and stress distributions were investigated by the finite element analysis software ABAQUS. The results indicate that the pressure-resistant capacity of the metallurgical composite bimetallic tube is equivalent to the internal metal in elastic state while the limiting inner pressure is much larger than the single metal tube with the same sizes in plastic state. The pressure-resistant capacity of the metallurgical composite bimetallic tube has increased more than two times compared with the external metal tube because of the transition layer which has a complete metallurgical bonding.
