FIELD: metallurgy.
SUBSTANCE: there is formed package in form of first and second titanium sheets with different granular structure laid in pile. Dimension of grain in the first titanium sheet at least approximately exceeds dimension of grain of the second titanium sheet. A fabricated package is heated, at least, to temperature of super-plastic moulding of the second titanium sheet. Super-plastic moulding of the said second titanium sheet is performed to production of profile of specified configuration and cells of the structure unit.
EFFECT: expanded process functionally for fabrication of structure units and their upgraded quality.
