| description | Theoretical studies of the endurance of an aviation alloy
of AMg6 type during its long-term cyclic volumetric
temperature deformation beyond the limits of Hooke's law
have been carried out. A technique has been developed for
assessing the endurance of aviation alloys in cyclic volumetric
temperature deformation taking into account the presence
of cavities (cracks) based on bringing the cyclic volumetric
temperature deformation conditions to the conditions of
standard mechanical testing of samples. According to
the developed method, a preliminary assessment of the
endurance of the aviation alloy of AMg6 type with a workhardened and annealed surface is carried out using the
available limited base of empirical data obtained on the basis
of standard mechanical tests of experimental samples. The
effect of the initial length of a crack in experimental samples
on the endurance of the experimental samples, at which
its uncontrolled growth is possible during cyclic volumetric
temperature deformation, is assessed. A comparative
analysis of the calculated endurance of the experimental
samples with the actual endurance of the structural material
(hard worked alloy AMg6) of a real orbital object such as
the «Zarya» module of the international space station shows
a discrepancy of no more than 12,5 %. |
