进行实验和数值分析来预测功能粉末/固体复合材料包层棒的变形参数。缺乏对结构粉末/固体复合材料包层棒（例如芯填充管（COFT））变形过程中的参数进行定量分析的理论方程。在本研究中，采用板坯法分析COFT拉拔过程，建立并求解静平衡方程以确定拉拔力、壁厚和芯密度。将新方程的预测结果与实验结果进行了比较，表明它们之间具有良好的一致性。方程和实验都表明在 COFT 拉伸过程中芯材存在最终相对密度。使用新方程确定了工艺参数对压实系数和芯材最终相对密度的影响。
Experimental and numerical analyses were performed to predict the deformation parameters of functional powder/solid composite clad rods. There has been a lack of theoretical equations for quantitative analyses of parameters during the deformation of structural powder/solid composite clad rods such as a core filled tube (COFT). In this study, a slab method was adopted to analyze the COFT drawing process, and static equilibrium equations were developed and solved to determine the drawing force, wall thickness and core density. The prediction results of the new equations were compared with experimental results, revealing good agreement between them. Both the equations and the experiments showed the existence of an ultimate relative density of the core material during the COFT drawing process. The influences of the process parameters on the compaction factor and ultimate relative density of the core material were determined using the new equations.
