SUMMARY:Anisotropy\, designing of the texture and mechanical properties of
  metal alloys - Prof. Eng. Carlo Mapelli\, Department of Mechanics\, Polit
 ecnico di Milano

CONTACT:Dr Sandra Korte
DESCRIPTION:The anisotropy of traditional industrial alloys is an inevitab
 le feature as a consequence of solidification and of the applied plastic d
 eformation. The mechanical anisotropy can be evaluated through the measure
 ments of Lankford coefficients and by the FLD (Forming Limit Diagram). The
  induction of specific anisotropy has not only detrimental effect\, althou
 gh a lot of engineers always work under the hypothesis of isotropy. Actual
 ly\, the anisotropy can be exploited to satisfy particular requirements (y
 ield strength\, elongation\, resistance against thinning etc.) along speci
 fic directions that are particularly interesting or critical for the final
  application. The anisotropy is a direct consequence of the as cast column
 ar structure or of the rotation induced during plastic deformation of the 
 crystal lattice. The induced crystallographic textures can be pointed out 
 by Inverse Polar Diagram\, Polar Diagrams and representation of the Orient
 ation Distribution Function. Examples of different crystallographic textur
 es and of the associated mechanical features will be presented for steels\
 , duplex stainless steels\, aluminium alloy α-β aluminium alloy. \n\n\n
