Mechanics Of The Solid-State Bonding Under Severe Thermomechanical Processes, Xue Wang
Mechanics Of The Solid-State Bonding Under Severe Thermomechanical Processes, Xue Wang
Doctoral Dissertations
Friction stir welding (FSW) has found increased applications in automotive and aerospace industries due to its advantages of solid-state bonding, no fusion and melting, and versatility in various working conditions and material combinations. The extent and quality of the solid-state bonding between workpieces in FSW is the ultimate outcome of their industrial applications. However, the relationship among processing parameters, material properties, and bonding extent and fidelity remains largely empirical, primarily because of the lack of the mechanistic understanding of (1) tool-workpiece frictional behavior, and (2) bonding formation and evolution.
In this dissertation, to study the underlying mechanism of tool-workpiece frictional …
