Abstract Scope |
Spray forming of thick dissimilar steel clad tubes can yield optimal combinations of mechanical and functional properties provided by the constituent materials with improved service lives and higher cost efficiency than conventionally cast monolithic components. Although significant progress has been made on the spray forming aspects of clad products, there has been limited progress on understanding how to promote interfacial bonding between the substrate and spray formed cladding important for downstream thermo-mechanical processing. High wear resistance tool steel was spray formed onto mild steel tubes with different substrate and spray temperatures. The interfacial bond integrity was quantitatively assessed by comparing the simulated residual stress distributions across the cladding-substrate interface with neutron diffraction measurements and the differences were used to infer the load transfer behaviour and thus the mechanical integrity of the interface.
The link between process parameters and the resulting microstructures, residual stress and integrity of the interface was revealed. |
