The effect of flash annealing on the mechanical and electrical properties of previously used AM2 mats composed of Al 6061-T6

Abstract Used AM2 mats (aircraft landing platforms) composed of Aluminum 6061-T6 were machined into tensile and conductivity bars. Samples were then subjected to five different temperatures: 315.6, 371.1, 426.7, 482.2 and 537.8 °C (600, 700, 800, 900 and 1000 °F), seven different time intervals (10, 20, 30, 70, 90, 120 and 150 s), and eight different exposure times (1, 2, 3, 5, 7, 10, 15 and 20 times). The ultimate strength, yield strength, and percent elongation of the samples were determined. Conductivity and hardness tests were also performed to assess the effect of thermal exposure.
