In this article, we present research results on the closing conditions of internal metallurgical discontinuities during the hot elongation operation of a Zr-1%Nb alloy ingot using physical and numerical modeling. Research on the influence of thermal and deformation parameters of elongation operations on the rheological behavior of a Zr-1% Nb alloy was conducted using the Gleeble 3800 metallurgical process simulator. Modeling of the influence of thermal-mechanical parameters of hot elongation operations in combinations of rhombic and flat anvils on the closure of metallurgical discontinuities was performed with the help of the FORGENxT 2.1 program. Based on the results of the research, recommendations were made regarding forging elongation technology and the geometry of working tools in order to ensure the closure of metallurgical discontinuities during hot elongation operations of Zr-1% Nb alloy ingots.
在本文中，我们展示了利用物理和数值模拟对Zr-1%Nb合金铸锭热拉伸过程中内部冶金不连续性闭合条件的研究结果。使用Gleeble 3800冶金过程模拟器，研究了拉伸操作的热参数和变形参数对Zr-1%Nb合金流变行为的影响。借助FORGENxT 2.1程序，对菱形砧和平砧组合的热拉伸操作热机械参数对冶金不连续性闭合的影响进行了模拟。基于研究结果，针对锻造拉伸工艺和工作工具的几何形状提出了建议，以确保在Zr-1%Nb合金铸锭热拉伸操作过程中冶金不连续性的闭合。
