摘要
观察并研究了纯铜高压扭转压缩阶段摩擦系数及凹槽结构对变形死区的影响,利用ANSYS有限元分析软件对其影响机制进行模拟仿真。结果表明,摩擦系数越大、凹槽深度越深、凹槽倾角越小,越容易产生死区。此外,压缩后纯铜试样等效应变的分部具有不均匀分布的特点:心部变形小、应变小,中间区域变形比较均匀,边缘位置变形大应变大。这一分布规律这与压缩后试样的显微组织分布、硬度分布相一致。
Effect of friction and anvil design on the dead metal of copper during the compressive stage of high-pressure torsion(HPT),using the finite element method,ANSYS code.The results indicated that DMZ is prone to be produced with higher friction coefficient,deeper cavity depth and lower wall angle.Otherwise,the effective strain distribution of copper are inhomcgeneous in the compression stage of HPT,exhibiting lower strain in center,higher strain in edge and uniform strain in radial medium of compressed disks.The distribution of effective strain is consistent with distributions of hardness and microctructure.
