“…The diagram indicates similar trend for the stress changes of the 0˚ and 45˚ angle of cutting samples and their mechanical strength values are slightly higher than those of 90˚ cut samples. The true strain values do not exceed 41% which has been highlighted in previous examinations [3,12]. The true stress of the material ranges from 110 up to 118 MPa.…”

“…For the purpose of improving its mechanical properties and plasticity Al is often alloyed with Mn and Mg and the materials thereof are used for higher levels of deep drawing. The behaviour of these alloys has been investigated by many authors [1][2][3][4][5][6][7][8][9] in order to determine the technological, mechanical, thermal, electro-chemical, etc. properties.…”

Abstract. Due to the generalized use of aluminium (Al) and Al alloy a detailed investigation of the mechanical and technological behaviour of a wide range of sheet metals is particularly needed. Often during deformation the Al sheets fold or crack which makes their subsequent use harder. The aim of this study is to identify the causes of the changes taking place during deformation that leads to earlier breaks of the Al sheet material. Pure ENAW-Al99.5 in as-received condition is used for examination in order to determine its behaviour without interference of the alloying elements. After the uniaxial uniform tensile test significant differences in the mechanical strength of the samples cut out from the sheet material at three different directions -0°, 45° and 90° angle to the rolling direction are observed. The hardness values measured at three different directions: alongside the long side of the samples, cross-section and top view are compared. The XRD and microstructure analysis confirm the grain and lattice reorientation after the tests compared with the initial structure of the sheet material. These results could be applied as a basis of comparison when examining other Al alloys used in aviation and mechanical engineering, chemical and agro-food industry, etc.
