摘要

利用自行设计的卡具在电子拉伸试验机上对高温下6061铝合金在4Cr5MoSiV1热作模具钢表面的粘附行为进行了研究

定量分析了成形温度和变形量对粘附现象的影响

观察了粘附后模具的微观组织形貌。结果表明

随着温度升高

铝转移量呈现先降低后升高的趋势

450℃时铝转移量最少

而后随着温度升高

粘铝现象变得越来越严重;随着铝合金变形量的增加

铝转移量先缓慢升高

当变形量为40%时

铝转移量迅速升高

粘铝现象开始变得严重。

Abstract

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.
