Way of Producing Porous-Free Long-Measured Blanks of Hot Extrusion
Journal Title: Հայաստանի գիտությունների ազգային ակադեմիայի տեղեկագիր․ Մեխանիկա - Year 2007, Vol 60, Issue 3
Abstract
The blank porosity dependence on extrusion conditions is established: coefficient of drawing ( λ ), pressure (P), yield point (C), angle of the die ( α ) and initial porosity ( θ 0 ) . Appropriate transformations of formulas obtained by the authors, as well as numerical calculations allow to get extrusion parameters for manufacturing porous-free long-measured blanks.
