Texture induced plastic anisotropy of rolled molybdenum sheets — •Ingwar Hünsche¹, Carl-Georg Oertel¹, Werner Skrotzki¹, Wolfram Knabl², Alexander Lorich², and Joachim Resch² — ¹Institut für Strukturphysik, Technische Universität Dresden, — ²PLANSEE Aktiengesellschaft, A-6600 Reutte/Tyrol, Austria

The microstructure, texture and mechanical properties of molybdenum sheets produced by PLANSEE AG in different rolling processes were investigated by orientation imaging in the scanning electron microscope, X-ray diffraction and tensile tests. Tensile tests were done in different directions of the rolled sheets. Results on the mechanical properties will be correlated with texture and microstructure of three different type of sheets. The texture of the sheets is characterized by components lying on the α - and γ -fibre typical for bcc metals ( α -fibre: ⟨ 110 ⟩ ∥ rolling direction, γ -fibre: ⟨ 111 ⟩ ∥ rolling plane). The different production processes used lead to changes in intensity of the components and thus to varying mechanical properties. The aim is to correlate microstructure and texture with mechanical properties in order to optimize the deep-drawability of the molybdenum sheets by modifying the production process.
