The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...

Abstract The resistance to chloride-induced stress corrosion cracking was investigated on a high-strength CrNiMnMoN austenitic stainless steel in the hot-rolled and different cold-drawn states. against determined by slow strain rate tests chloride containing solutions at elevated temperatures. A fracture analysis carried out using scanning electron microscopy. Improved is obtained formation of ...

In this study, a superelastic Ti-18Zr-15Nb (at. %) alloy was subjected to thermomechanical treatment, including cold rotary forging, intermediate annealing, drawing, post-deformation and additional low-temperature aging. As result of two structures β-phase were obtained: fine-grained structure (d ≈ 3 µm) coarse-grained 11 µm). Cold drawing promotes grain elongation in the direction; state, grai...

Abstract The present review paper would celebrate the 25 years anniversary of ESAFORM association by summarizing studies performed delegates conference series within mini-symposium “Extrusion and Drawing” papers published in International Journal Material Forming same fields. 160 analyzed have been divided four main categories corresponding to chapters (Hot Metal Extrusion, Cold Polymer Extrusi...

The fracture performance of axisymmetric notched samples taken from pearlitic steels with different levels cold-drawing is studied. To this end, a real manufacture chain was stopped in the course process (on-site factory), and all intermediate stages were extracted initial hot-rolled bar (not cold-drawn at all) to final commercial product (prestressing steel wire). Thus, drawing intensity or st...

This report describes the Fifth Annual Graph Drawing Contest , held in conjunction with the 1998 Graph Drawing Symposium in Montreal, Canada. The purpose of the contest is to monitor and challenge the current state of the art in graph-drawing technology 4, 5, 6, 7].
