As we know, the Al3Sc particles are initially fully coherent with the matrix,and there are at least three possible grain boundary/dispersoid interactions when an advanceing high angle grain boundary is passing a coherent Al3Sc dispersoid: The Al3Sc dispersoid retains its global orientation relationship and thus loses its coherency with the surrounding matrix; The Al3Sc dispersoid rotates as the grain boundary passes; The Al3Sc dispersoid dissolves at the grain boundary and re-precipitates in the recrystallised grain.

Introduction Ultra-high strength steels (UHS) and high strength steels (HS) are advanced materials providing a combination of strength, ductility, toughness, high strength to weight ratio, ease of manufacturability and cost effective manufacturing.
High strength steels with fine grains possess good weldability and plastic deformability, and thus they are promising engineering materials for the future.

Study of Mechanical Properties and Modeling of Flax Reinforced Composites Pavel Srb1,a*, Martina Syrovátková1,b, Petr Kulhavý1,c, Blanka Tomková2,d 1The Institute for Nanomaterials, Advanced Technology and Innovation, Technical University of Liberec, Studentská 1402/2, Liberec, 46001, Czech Republic 2Technical University of Liberec, Studentská 1402/2, Liberec, 46001, Czech Republic apavel.srb@tul.cz, bmartina.syrovatkova@tul.cz, cpetr.kulhavy@tul.cz, dblanka.tomkova@tul.cz Keywords: flax prepreg, composite material, mechanical properties, tensile, layer orientation.
The resulting composites, which are a combination of fibres with plastic matrices, have excellent mechanical properties and they are used in the aerospace, energetic, automotive, engineering industry and many others, not only in technically oriented industries [1].
Linear elasticity in an orthotropic material is most easily defined by giving the engineering constants (three elastic moduli, Poisson’s ratios and shear moduli) associated with the material’s principal directions.
Engineering constants using in numerical model are given by Table 4.
