EFFECT OF NEUTRON RADIATION ON CERTAIN MECHANICAL AND STRUCTURAL PROPERTIES OF AUSTENITIC CHROME NICKEL STEEL
Abstract
The change of mechanical and structural properties of 13 kinds of anticorrosive steels of Cr-Ni-type exposed to integral dose of 1,6.1019 n/cm2 was investigated. The dose was held at a constant value and the chemical composition varied namely in the Cr and Ni content. The strengthening was observed, i.e. yield point, strength and hardness increased and plasticity decreased at the same time. Primary the rate of strengthening is independent on chemical composition, namely on chrome and nickel content, however is depends on the physical condition of steel before the radiation. As far as the alloying elements do not influence the properties in initial condition of steel, they exercise no influence also on the properties in initial condition of steel, they exercise no influence also on the radiation stability. Ferromagnetic induction measurement indicated the decrease of corrosion resistance of austenitic steels by radiation to be negligible. Transient auste0 nitic-ferritic structure steels only show a .43-0.72% increase of magnetic phase caused by gamma to alpha decay.
