Abstract

In conventional welding methods, such as those used in joining ceramic-reinforced aluminum matrix composites, a variety of problems occur. For instance, the element used for reinforcement, which increases the viscosity in the melting stage, makes the mixing of matrix and reinforcement material difficult, and this causes inferior joining quality and makes the establishment of welding difficult. Also, chemical reactions and undesirable phases are observed because there is a difference between the chemical potential of the matrix and reinforcement material. In this study, joining a SiC particulate-reinforced A356 aluminum alloy and AISI 1030 steel by continuous drive friction welding was investigated. The integrity of the joints was also investigated by optical and scanning electron microscope (SEM), and the mechanical properties of the welded joints were assessed using microhardness and tensile tests. The results indicate that an aluminum matrix composite and AISI 1030 steel can be joined by friction welding.
