Effect of Nitrogen Impurities on GS30-VI Ni-base Superalloy Single-Crystal Structure and the Development of its Efficient Refinement Methods

The relationship was determined between the nitrogen content in GS30-VI alloy and the single-crystal blade rejects due to the formation of equiaxial "parasitic" grains. The efficient method for refining the melt against the nitrogen impurities under the conditions of vacuum induction melting envisaged the heat treatment with the predetermined time, which allowed to ensure the nitrogen content in metal at the level of <0,001% (by weight).

Lightning resistance of the present-day polymer composites

The lightning-protective coating (LPC) was developed on the base of carbon fillers and polymer binders, modified by nanoparticles, ensuring the reliable protection of bearing carbon fiber reinforced plastic (CFRP) structural elements, applied in the outer airframe contour against through holes, burn-outs splittings, appearing, as a result of shifting lightning discharges effect with the parameters of I=200 kA and Q=20 C. The LPC application allows: to reduce inner fractures of directly structure bearing parts; to create multivector for lightning current scattering; to minimize the matrix effect, as a dielectric; to increase the transversal heat- and electroconducting characteristics of a composition by more than 2,5 times; to reduce considerably fractures, appearing due to destructive processes at the expense of matrix heat resistance; to exclude a product weight increase as LPC is included into the calculative diagram of bearing structures. The recommendations have been developed FCRP compositions designating for the lightning protection of components and aggregates, applied in the outer aircraft fuselage surfaces (at the skin thickness of <2,5 mm) in the zone of shifting lightning discharges with the parameters: I=200 kA and Q=20 C.

Composite material based on plumbum

The Pb-(Al-Cu-Fu) quasi-crystal composite material, doped with boron was produced. Composite on the base of plumbum exceeds polymer antifriction materials and pure plumbum in strength properties but yield to babbit of БС type, however, the operating temperature range is wider, as compared to composite materials. The strength properties of Pb-base composite are increased from 30 to 40 MPa at - 100°C. Opposite to matrix material, the composite material has higher rigidity and it’s not subjected to bending when touching with cutting instruments, which allows to produce the low-listed products of it.

Keywords: composite material, plumbum, Al-Cu-Fu quasi-crystal

Residual stress relaxation in aircraft organic glasses at the post-flight

The tensile stress relaxation process was experimentally studied by developing the high-elastic deformation (HED) for CO-120 and VOS-2 organic glasses along with the residual stress relaxation process associated with the HED disappearance during the aircraft post-flight rest. It was stated, that the significant differences were not observed during the residual stress relaxation processes in glasses of various structures and the relaxation regularity of residual stresses, produced at the service temperature close to the glass softening one was closely approximating to the regularity of the tensile stress relaxation at the room temperature.

Keywords: high-elastic deformation, residual stresses, relaxation, organic glass
