dc.description.abstract | Desire for efficiency and weight reduction in engines has propelled the search for lightweight alloys which retain high mechanical strength at extreme temperatures. A novel aluminum cerium alloy system was developed as a solution; the alloy’s production is inexpensive, and it has exceptional castability and strength at temperatures >300ºC where a typical aluminum
alloy would see significant reduction in mechanical properties. There is currently no published research on the friction stir welding (FSW) behavior of cerium-alloyed aluminum. FSW of this material would have numerous applications in the space sector and could also provide a means of repair of costly castings, returning cracked castings to near cast properties. In this thesis, the FSW behavior of an aluminum cerium alloy (Al-10Si-7Ce-4.3Cu-0.4Mg) is examined and resulting weld properties are presented; through implementation of high rotational speeds and slower traverse rates than are used for traditional aluminum FSW, an initial weld profile was formulated and adequate friction stir welds were achieved. | |
