Unlike of our previous report the method suggested takes into account consideration the initial stage of superplastic forming, when the pressure of the inert gas changes from the initial zero level to a pre-given constant value.  It is shown that such kind refinement enables one to improve considerably the accuracy of calculating the value of the strain rate sensitivity index, m, and, as a result, to provide more accurate finite element description of the superplastic forming processes.

This work is devoted to the search for such values of the interaction parameters and the intensity of external fields in a three-layer multiferroic film , at which nontrivial topological magnetic structures are stable in the ground state. To reduce the computational complexity of searching in the parametric space, we use the apparatus of artificial neural networks

(a) Scheme of an arbitrary pole of the sample surface (the edge of every round disc is made up of atoms at the step edges and atoms at the edge): A, C – atoms in the step edge; B – atom in the center of the plane (half of atoms bonds are broken); D – separately placed atom at the edge of the plane (has one non broken bond). 
(b) Field ion image of the disordered state of the alloy Fe25Pd50Au25. The statistical arrangement of atoms in the crystal lattice shows a chaotic contrast of the surface image.
(c) Field ion image of the ordered state of Fe25Pd50Au25 alloy. Fe and Au atoms provide contrast in the field ion image, Pd atoms do not provide contrast.

The thermokinetics of shape recovery after bending of Ni-rich titanium nickelide was studied. Loading–unloading procedure was carried out in various phase states using isothermal and non-isothermal modes varying loading strain. The two-stage character of shape recovery under heating is revealed; the hypothesis of its origin is suggested.
