Billets and methods for manufacturing them are disclosed. The billets include a cladding member including an alloy selected from the group including stainless steel, nickel-chrome, nickel-copper, and copper-nickel alloys, and a steel body that is positioned so that it has an interface with the cladding member, the steel body having a formation in which the scavenging metal is located and elements being provided for separating the scavenging metal from the cladding member at the interface.

A thermal-assisted method deforms a sheet metal assembly having constrained ends. A focus bending area located between the constrained ends is heated. The focus bending area is bent while the sheet metal assembly is within an elevated bending temperature range. A sheet metal assembly may be formed by this method, which includes an outer metal sheet and an inner metal sheet fixed together to form constrained ends. The sheet metal assembly has a bend formed therein between the first and second constrained ends, wherein each metal sheet is bent at the bend with a maximum gap between the inner and outer metal sheets at the bend. The maximum gap is no greater than five times the thickness of one of the inner and outer metal sheets, and the bend has a radius less than three times the thickness of one of the inner and outer sheets.
