Effect of heat treatment on the bending behavior of STS/Al/STS hybrid metal plates
The microstructures and bending properties of STS439/Al1050/STS304 clad plates were investigated after annealing process at various temperatures.Interfacial layer was developed at the STS439/Al1050 and All050/STS304 interfaces at 550℃.The presence of Al3Fe2 at the STS/Al interface was confirmed by EDX.The initial bending hardenability and load under condition A (STS439 side in tension) was found to be greater than under condition B (STS304 side in tension).The higher hardenability and load under condition A can be explained by the greater strain hardenability of STS439 (bottom side) in tension.No interfatial cracks were observed across the interface in the as roll-bonded clad composite and annealed clad composites at 450℃.After annealing at 550℃, the load drops in the early part of load-displacement curves associated with the interface debonding was observed.As-rolled clad metal and that annealed at 450℃ exhibited the relative high load.
