The aluminum adhesive behavior of 6061 aluminum alloy was analyzed under the high temperature on the surface of 4Cr5MoSiV1 hot work die steel with the self-designed fixture on electron-tensile tester.The effects of the forming temperature and deformation on the aluminum adhesive were analyzed quantitatively

and aluminum adhesion microstructure was observed.The results indicate that the aluminum transfer mass is increased firstly and then decreased with the increase of the heating temperature.It is found that the least amount of aluminum transfer mass can be obtained at 450℃

and the phenomenon of aluminum adhesive becomes more and more serious with the increase of temperature.The aluminum transfer mass shows a trend of increasing slowly firstly and then increasing drastically with the increase of the deformation rate.When the deformation rate is more than 40%

the phenomenon of aluminum adhesive becomes more serious.
