Abstract

Effects of aging treatment on microstructures and properties of 6101 Al alloy were investigated by means of optical microscopy

EDS

tensile machine

hardness testing and electrical conductivity testing

especially for effects of aging temperature and aging time on the mechanical properties and electrical conductivity of 6101 Al alloy.The results reveal that the yield strength and hardness of aluminum alloy are increased with the increase of temperature at 120

60 ℃.At a given aging temperature

the strength and hardness of aluminum alloy are increased with the increase of aging time.The optimal aging treatment for 6101 Al alloy is at 140 ℃for 8h.
