“…A failure criterion is necessary to model the material behaviour upon the nucleation of damage and beyond the point of necking, to accurately simulate the later stages of the forming process [15,17]. For non-isothermal processes, coupled thermo-mechanical simulations are conducted using temperature dependent material models, to account for the heat transfer between the blank and the tool parts [18]. The interfacial heat transfer coefficient in such a process can be predicted accurately using numerical methods [19].…”

a b s t r a c tAn FE model of the solution heat treatment, forming and in-die quenching (HFQ) process was developed. Good correlation with a deviation of less than 5% was achieved between the thickness distribution of the simulated and experimentally formed parts, verifying the model. Subsequently, the model was able to provide a more detailed understanding of the HFQ process, and was used to study the effects of forming temperature and speed on the thickness distribution of the HFQ formed part. It was found that a higher forming speed is beneficial for HFQ forming, as it led to less thinning and improved thickness homogeneity.

“…Forming technology in warm conditions, typically below 0.5 T m where T m is the absolute melting point, has received considerable attention over a period of many years [1][2][3][4][5]. Currently, increasing interest in nonisothermal forming for non-ferrous sheets, such as aluminium alloys, is being driven by weight-reduction trends as well as precision forming technology.…”

The Effect of Temperature on Anisotropy Properties of an Aluminium Alloy

International audienceThe temperature influence on the mechanical behaviour during plastic deformation of an AA5754-O aluminium alloy has been investigated by several experimental tests. First, monotonous tensile tests were carried out from room temperature up to 200°C with a classical tensile machine and with a less conventional testing apparatus involving the heating of the sample by Joule effect. With this second testing apparatus, the strain fields and tensile curves were obtained in function of temperature by means of a non-contacting optical 3D deformation measuring system. Moreover, shear tests were performed in the same temperature range. It is shown that the anisotropy coefficients are rather constant within this temperature range, with a relative variation less than 8%. For both tensile and shear tests, the stress levels are similar at the beginning of straining at room temperature and 150°C, except that the Portevin-Le Chatelier (PLC) phenomenon disappears at elevated temperature, and then evolves differently. At 200°C, the stress level is clearly below whatever the deformation. In the framework of drawing process, the formability of this alloy at temperatures higher than 150°C seems to be improved

The purpose of warm forming is to reduce the deformation resistance, and therefore the formation of products at reduced pressures. A key problem associated with warm sheet metal forming is uniform heating of the material to a required temperature. This task is carried out mostly by using resistance heating plates. The article presents the results of the analysis of the thermal state of a heating plate for induction heating of an AMS 5604 stainless steel sheet. To determine the temperature distribution on the sheet surface an FLIR P 640 thermal imaging camera was used. It was found that the temperature difference on the outer surface of sheets preheated to the temperature of 900°C was about 300°C. A large difference in the temperature on the outer surface of the sheet means that the analysed device cannot be successfully used in the heating process of stainless steel sheets. After the application of a layer of graphite on the sheet surface to increase the emissivity, areas of low emissivity as a result of graphite detachment from the sheet surface were observed.
