Effect of Aging Process on Mechanical Properties of 6082 Aluminum Alloy Extrusion Bar
The 6xxx series aluminum alloys has attracted much attention owing to good strength,excellent formability and corrosion characteristics.The mechanical properties can be significantly improved by age-hardening.The effects of different aging system on the mechanical properties of 6082 aluminum alloy extru-sion bar were studied.The experimental results showed that the aging time could be shortened significantly by using higher aging temperature,and the yield strength could be reached or exceeded in a shorter time compared to the aging process of 175 ℃ ×8 h.Especially when the temperature exceed 195 ℃,the aging time could be shortened to 1 h,which not only reduced the energy consumption,but also improved the production efficiency.
