@article{(Open Science Index):https://publications.waset.org/pdf/9998136, title = {The Strength and Metallography of a Bimetallic Friction Stir Bonded Joint between AA6061 and High Hardness Steel}, author = {Richard E. Miller}, country = {}, institution = {}, abstract = {12.7-mm thick plates of 6061-T6511 aluminum alloy and high hardness steel (528 HV) were successfully joined by a friction stir bonding process using a tungsten-rhenium stir tool. Process parameter variation experiments, which included tool design geometry, plunge and traverse rates, tool offset, spindle tilt, and rotation speed, were conducted to develop a parameter set which yielded a defect free joint. Laboratory tensile tests exhibited yield stresses which exceed the strengths of comparable AA6061-to-AA6061 fusion and friction stir weld joints. Scanning electron microscopy and energy dispersive X-ray spectroscopy analysis also show atomic diffusion at the material interface region. }, journal = {International Journal of Industrial and Manufacturing Engineering}, volume = {8}, number = {5}, year = {2014}, pages = {392 - 396}, ee = {https://publications.waset.org/pdf/9998136}, url = {https://publications.waset.org/vol/89}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 89, 2014}, }
