A Numerical Study of the Effect of Extrusion Parameters on the Temperature Distribution in Zr-2.5Nb

摘要

A three-dimensional finite element method (FEM) analysis of the hot extrusion process of Zr 2.5 %Nb was carried out. Simulations were carried out for bringing out the role of extrusion temperature, extrusion ratio, ram velocity, and profile of die on the extrusion process. The effect of these process parameters on the overall temperature distribution and hence on the resulting microstructural and textural homogeneity or lack of it is discussed. FEM analysis allowed for the quantification of the extent of differences in temperature distribution between leading and trailing end and also across a given cross section.
