Mechanical Properties of 5000 Series Aluminum Alloys Following Fire Exposure

High rate and temperature-dependent tensile characterisation with modelling for gap-bridged remote laser welded (RLW) joint using automotive AA5182 alloy

“…In general, 5xxx series alloys are strain hardened and predominantly attain strength through grain refinement. Fine grains restrict the movement of dislocations resulting in increased strength [75]. At lower temperature (150-250 °C), a partial loss of strength occurs due to subgrain coarsening and dilution of the Mg solid solution content in the aluminum matrix [76].…”

Mechanical Properties of Strengthening 5083-H111 Aluminum Alloy Plates at Elevated Temperatures

“…Various aspects of the high-temperature performance of this alloy have been investigated in previous studies [22][23][24][25][26][27][28][29]. Summers et al [22,23] studied post-fire residual mechanical properties of 5083-H116, 6082-T651, and 6082-T6 aluminum alloy extrusions.…”

“…The predictions of the residual yield strength and strain hardening of the developed constitutive model showed good agreement with that of the experimental results. Free et al [26] carried an experimental investigation to study the change in microstructure and mechanical properties of six different 5000 series aluminum alloys following a simulated fire exposure. Guo et al [27] studied the mechanical properties of certain brands of aluminum alloys (AA6061, AA6082, AA6N01, AA7020) at temperatures that ranged from −100 to 300 • C. They concluded that the AA strength and ductility improved at low temperatures and their mechanical properties (elastic modulus, ultimate strength, nominal yield strength) dropped rapidly at high temperatures.…”
