| Gaia: | Заглавие с экрана The work studied formation of the structure and physicomechanical properties in iron-nickel invar alloys obtained by sintering powders. The sintering of Fe and Ni powders leads to the formation of the face centered structure with the lattice parameters, which correspond to invar compositions. The significant microdistortions in the alloy are formed, apparently due to the formation of concentration inhomogeneity with increase of the sintering temperature. The phase with a body centered structure released with sintering of the system. It is shown that the minimum pore size corresponds to a concentration of 36 mass. % Ni and is 11 [mu]m at 1300 °С and 15 [mu]m at 1350 °С. Sintered invar alloys have a comparable microhardness value, compared with the literature data, and equal to 1215 MPa (Fe-36 % mass. Ni at Ts=1350 °С). |
