Characterization of the evolution of 2219-T87 aluminum as a function of the friction stir welding process
نویسندگان
چکیده
The aluminum-copper alloy AA2219 is commonly joined by friction stir welding (FSW). strengthening Al2Cu phases are affected the temperatures produced as a function of FSW process. This work characterizes effect on fatigue crack growth and fracture response AA2219-T87. Specifically, virgin material’s microhardness, strength, θ-phase evolution studied time temperature. data compared to microhardness resulting in zone, thermo-mechanically zone (TMAZ), heat (HAZ), base material. Furthermore, residual stresses process quantified.

Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages. Laser Assisted Friction Stir Welding (LAFS...
