“…A forming analysis of clad tube and base tube in spinning process was conducted by numerical simulations and experiments. The results indicated that as the press amount (δ) increased, the strain of clad tube changed more than base tube and as the feed rate increased, the strain decreased in axial direction and tangential direction but almost unchanged in radial direction [15]. The spin forming parameters of bimetallic composite pipe were optimized by FEM and experiment in my previous research, and the torque and the residual contact pressure were analyzed during forming process.…”

Bimetal composite pipe are widely used in petrochemical industry and other industries due to its good mechanical properties and corrosion resistance. In this paper, the minimum radial rotary pressure (Pimin) and maximum radial rotary pressure (Pimax) were obtained by theoretical mechanical calculation, so as to optimize the design of the spinning device. The residual contact pressure was acquired to evaluate the forming quality of the composite pipe. It was found that when the spinning parameters (δ = 0.16 mm, ψ = 0.4 mm, β = 3.0° and f = 0.5), the maximum residual contact pressure was obtained, and the simulated and experimental values were 9.19 MPa and 9.01 MPa, respectively. They were close to the theoretical value (9.67 MPa), and the error of these values was about 9%, which proved the accuracy of the theoretical analysis.

“…Bimetallic materials generally have superior comprehensive properties which are extremely di cult to achieve for single metal materials [1][2][3]. Comparing to other bimetal bonding processes, the solid-liquid bimetal compound casting has been extensively used in modern industry with the advantages of good interfacial bonding quality, high production e ciency and wide range of applicable alloys, etc.…”

A practical bimetallic casting consisting of aluminum matrix and cast iron inserts was manufactured via high pressure die casting (HPDC) process. Different surface treatment methods of the cast iron inserts, including salt membrane plating and electrogalvanizing, were adopted to improve the bonding quality of bimetallic castings. Microstructure characterization on the bonding interface was conducted at different locations of bimetallic castings. Results indicate that compounds with awless and continuously metallurgical bonding interface can be successfully fabricated by the HPDC process with the zinc rack plating treatment on the surface of cast iron inserts which results in a dense zinc coating with an average thickness of 8 μm. The melt ow speed and heat transition during solidi cation of the HPDC process are two key factors in determining the bonding integrity of bimetallic castings. With the dissolution and diffusion of the very thin zinc coating during solidi cation, there is no obvious aggregation of zinc element at the metallurgical bonding interface. Instead, a reaction layer with an irregular tongue-like morphology is formed with an average thickness of approximately 1 μm while it mainly consists of intermetallic phases Al 60 Cu 30 Fe 10 and Al 2 FeSi, etc.

“…During the experiment the bonding strength of the Al/Fe bi-metal pipes was described, on the basis of which the signi cant process parameters were determined, including the radial gap, discharging voltage, and feeding length. Jin [10] analysed the forming characteristic of the Cu/al bi-metal pipes, i.e. a clad pipe and a base pipe, that emerged during the spinning process using a variety of simulations and experiments.…”

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. The production of pipe bends with a supercritical bend of 0.7D, which form the part of serpentine systems, is very complex and technologically demanding, because very often undesired cracks occur. To increase the service life of these serpentine systems, the use of a 16Mo3 base steel pipe with a cladding layer of Inconel 625 material was proposed for their production in order to signi cantly increase their corrosion resistance. For this reason, an extensive analysis of the production of pipe bends with a supercritical bend of 0.7D from bimetal pipes with Inconel 625 cladding was performed, which addressed not only the bend but also the mechanical properties of the pipe with Inconel 625 cladding. It was found out that the production of the pipe bend with a bend of 0.7D of a bimetal pipe is feasible completely without defects with perfectly satisfactory mechanical properties.
