Abstract
A sample made from a ribbon of austenitic-martensitic steel 0.3C–13Cr–10Mn–3Si–1V, pre-deformed in the shape of a circular arc with a deflection of 3 mm, was subjected to fast neutron irradiation with a fluence of 6 × 1019 cm–2 in the vertical wet channel of the IVV-2M reactor at a temperature of 80°C. This material belongs to the class of stainless manganese austenitic steels with the shape memory effect (SME). Initially, it was expected that irradiation would reduce the SME magnitude after subsequent heating of the studied sample in comparison with the reference one. But instead, the manifestation of SME was revealed already after irradiation, with a decrease in the deflection by approximately 21%. Control experiments confirmed that the lower temperature limit for the manifestation of the SME in this material lies at 120ºC and is absent at 80°C. This allows us to conclude that the effect observed is the result of neutron irradiation.
期刊介绍：
The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
