“…With the criterion for void closure, process design and optimization in terms of elimination of voids in large ingots will be convenient since the criterion can be easily applied in CAE analysis. 2)) is the Norton-Hoff equation (Boër et al, 1985;Gegel et al, 1998;Hoff, 1954;Lubliner, 1990;Poursina et al, 2008) which is widely used for metals at high temperature.…”

The compression test provides a useful information about the material flow under large plastic deformations, when compared to the standard tensile test. On the other hand, it is heavily dependent on the lubrication conditions. The paper deals with two different specimen geometries resulting in two different friction conditions. The first geometry corresponds to the classical smooth cylinder. The second one was designed according to the idea of Rastegaev. It is a smooth cylinder with grooves on both faces (bases), which allow the lubricant to accumulate and prevent it from escaping the region, where the punches are in the contact with specimen. Then, both cases were computationally simulated and compared with experiments.

“…With the aim of performing a proper material characterization to obtain the viscoplastic behavior of the steel, the steps presented by Poursina et al [19] were followed and tests were carried out at 800, 950, 1100 and 1300 ºC at different strain rates, 0.001, 0.1, 1.0 and 10 s -1 .…”

The aim of this paper is to present the developed procedure for the simulation of the hot rolling process also referring to some patents. Rolling is a 3D process but using the generalized plane strain method, the real 3D problem can be solved using 2D Finite Element Model (FEM), saving an important computing time. Thus, this procedure is really useful to give assistance in the roll design and to obtain the stock cross-section temperature distribution in the whole rolling process. On the other hand, it is also presented the thermo-mechanical characterization of the R260 quality steel, 0.7% C pearlitic steel, commonly used in rail rolling. Finally, the procedure is applied to simulate the UIC-60 rail hot rolling. A good agreement between FEM results and the sample shapes was obtained in the ArcelorMittal, S.A. rail mill facility in Asturias (Spain).
