Abstract
We study the influence of hydrogen on the parameters of atomic ordering Kurnakov temperature T K and longrange atomic order η in N36 alloy doped with carbon It is shown that the dissolved hydrogen increases the parameter η for the FeNi structure by 25 at a constant temperature T K It is shown that the procedure of doping with carbon 026 wt leads to an increase in T K by 12–15°K In the doped N36 alloy the ultimate strength σu increases from 300 to 360 MPa at 293°K and the additional heat treatment in hydrogen aimed at the atomic ordering enables us to increase σu to 440 MPa The plasticity of the samples remains practically constant δ = 20 The physical mechanism of the outlined influence of interstitial impurities is proposed
