SUMMARY:Hrushko: Features of the study of mechanical properties of material
 s with dynamic recrystallization by applying the phenomenological approach
CLASS:PUBLIC

 ties of functional materials is a link necessary for both technological pr
 ocess calculations for product manufacturing and optimisation of technolog
 ical routes. Such properties include elasticity characteristics - Young's 
 modulus\, Poisson's ratio\, plasticity characteristics - flow curves and l
 imit characteristics before fracture. Mn-Al base alloy\, as one of the pro
 mising magnetic alloys worked which IFW is working\, is of considerable in
 terest from this point of view\, but the existing data on its mechanical p
 roperties are limited.  Also at processing temperatures\, this material ex
 hibits a dynamic recrystallisation phenomenon\, which can and has to be us
 ed as an important property to reduce the deformation resistance. The math
 ematical model in this case should take into account the strain value\, te
 mperature and rate factor\, which allows to establish an appropriate optim
 isation problem. A macro-level phenomenological approach based on heredity
  theory for this type of modelling is the most promising from a practical 
 point of view.   The present talk is dedicated to the presentation of exis
 ting approaches\, the justification of possible solutions and a preliminar
 y analysis of the data obtained.
