13. Efeito do ângulo da fieira na geometria e propriedades mecânicas de barras trefiladas
In cold drawing of metallic bars most of the plastic flow is caused by compressive forces which arise from the reaction of the metal to the die. Due to the characteristics of the process this flow is not homogeneous along the cross section of the bar and is influenced by the die geometry. This inhomogeneous deformation generates residual stresses in the bars

14. Heterogeneidades mecânicas e microestruturais durante o processo de trefilação combinada do aço SAE 1045
Este trabalho estuda o processo de trefilação combinada do aço SAE 1045, que consiste nas etapas de pré-endireitamento com múltiplos rolos, jateamento, trefilação, corte e endireitamento por rolos, tendo como produto final barras acabadas trefiladas. Este produto final é empregado na fabricação de hastes de amortecedores para indústria automotiva.

15. Sensitivity analysis of the ECAE process via 2k experiments design
In this work the theoretical solutions based upon the upper-bound theorem recently proposed by Pérez and Luri [Mech. Mater. 40 (2008) 617] for the equal channel angular extrusion process (ECAE) are analyzed by performing a 25 central composite factorial analysis. The uniaxial mechanical properties of commercial pure aluminium are considered by assuming isot

16. Internal adaptation of cast titanium crowns
As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were

17. Numerical and experimental analysis of tube drawing with fixed plug
Numerical simulation of manufacturing processes has become in the last years an important tool to improve these processes reducing lead times and try out, and providing products free of defects and with controlled mechanical properties. Finite Element Method (FEM) is one of the most important methods to simulate metal forming. In tube drawing with fixed plug
