Abstract

This paper described the thermal stress and fracture of friction-welded joint between pure nickel (Ni) and pure aluminum (Al) with post-weld heat treatment (PWHT). FEM model of the joint with the NiAl interlayer at the weld interface, of which was generated as the intermediate layer consisting of intermetallic compound, was constructed. Then, FEM thermal elastic–plastic analysis was carried out, and the fracture factor of the joint during the cooling process after PWHT was described from the calculation and experimental results. The calculated thermal stresses at the adjacent region of the weld interface for the joint, due to the difference of material properties between both base metals, occurred at the early stage during the cooling process. However, the thermal stress was relatively low and had a little effect on the joint fracture. All thermal stresses of the joint with the NiAl interlayer width of 200 μm were smaller than those of 20 μm. Actually, the joint fractured between NiAl interlayer and Al side, of which was like as disbonding in the experiment. Hence, one of the main reasons for the fracture of the joint was able to be thought that the bonding strength between NiAl interlayer and Al side decreased with increasing NiAl layer width, because the thermal stress was low. Therefore, the fracture portion will be changed according to combinations of both base metals to be joined for dissimilar friction-welded joints.
