Abstract:

This research explores the effect of elevated extrusion ram speed—achieved through die cooling with liquid nitrogen—on the mechanical behavior of 6060-aluminum alloy profiles. Mechanical characterization was conducted via tensile testing and nanoindentation, with the latter also employed to assess the alloy’s creep response. Results reveal that while the increased ram speed exerts minimal impact on Ultimate Tensile Strength (UTS) and Yield Tensile Strength (YTS), it notably enhances elongation. Furthermore, the study demonstrates a significant influence of ram speed on creep displacement as the dislocations generated by higher ram speeds seems to improve the creep resistance of the material. Keywords: 6060 Aluminum Alloy; Liquid Nitrogen Cooling; Nanoindentation; Tensile Testing; Creep Behavior.
