Thermomechanical coupled numerical simulation of GH4169 alloy for cross wedge rolling

  • 摘要: 采用有限元软件DEFORM-3D对GH4169合金的楔横轧成形进行了热力耦合数值模拟,得到了GH4169合金轧件的金属流动情况、温度场的分布规律以及轧件与轧辊间的轧制力和力矩,并与45#钢进行了对比分析.结果表明:在楔横轧成形中,GH4169合金轧件的轴向金属流动规律不同于45#钢,其外层金属的轴向流动大幅度滞后于心部;各力能参数都要大于45#钢,且最高为45#钢的2.15倍;变形温度始终高于45#钢,最高温升比45#钢多6.21%.
    Abstract: Thermal-mechanical coupled numerical simulation of GH4169 alloy during cross wedge rolling(CWR) was carried out using the finite element software DEFORM-3D.The metal flowing and temperature distribution of rolled pieces,and the rolling force and torque between the rolled piece and the roller were obtained and comparatively analyzed with 45# steel.The results show that the axial metal flowing of GH4169 during CWR is different from that of 45# steel,and the axial metal flowing at the surface substantially lags behind that at the center.All the energetic parameters are much greater than 45# steel's,and the maximum value is 2.15 times that of 45# steel.Meantime the deformation temperature is always higher than 45# steel's,and the maximum temperature rise is 6.21% more than that of 45# steel.
