Abstract

The orthogonal experiment was designed for heat treatment of ZL102 aluminum alloy.Combined with the tensile strength test

range analysis and variance analysis of orthogonal results were carried out.The desirable heat treatment parameters for aluminum alloy were presented as follows:solid solution treatment at 500 ℃for 7hand aging treatment at 220 ℃for 3h.Effects of heat treatment on mechanical properties of ZL102 alloys were investigated by wheatstone bridge conductivity measurement

optical microscope and scanning electron microscope.The results indicate that

tensile strength and hardness of ZL102 are improved dramatically after heat treatment

and conductivity can also be improved.Consequently

the heat treatment system is feasible.
