“…Therefore, the development of steels is aimed at stainless steels and their improvement, due to their wide use in cryogenic temperatures as a structural material in fusion reactors to the red-hot temperatures of furnaces and engines [4][5][6][7]. For devices operating at liquid helium temperatures, such as conductor conduits for the International Thermonuclear Experimental Reactor (ITER) magnet system, 316LN-IG stainless steel is used [8]. The presence of chromium secures the excellent corrosion resistance of these iron-based alloys at a minimum of about 12 wt.%.…”

The article deals with increasing the mechanical properties of stainless steel 316 Ln-IG, which is intended for work in cryogenic temperatures (liquid nitrogen and liquid helium), such as conductor conduits for the ITER magnet system. The strength and plastic properties were increased by a combination of cold and cryo-rolling and heat treatment. The mechanical properties of rolled material were investigated at 293 K, 77 K, and 4.2 K. The work-hardening rate of the steel increased continuously with a lowering of the temperature. The maximum yield strength and ultimate tensile strength were achieved by the cryo-rolling process with a total thickness deformation of 50%. The material properties tested at ambient temperature were 0.2YS = 1050 MPa, UTS = 1200 MPa, and at 4.2 K, the values were 0.2YS = 1804 MPa and UTS = 2081 MPa. Two types of long-term heat treatment were applied after experimental rolling (823 K and 1093 K for 10 h). The highest precipitation hardening of steel was achieved at a temperature of 823 K after 50% deformation. The resulting grain size decreased from the initial 216 μm (before the rolling process) to 70 μm after ambient rolling and 72 μm after cryo-rolling.

“…A phenomenon that can be used to monitor stresses in the constructions is the magnetoelastic effect [4,5]. The magnetoelastic effect is a change of the magnetic properties under stress [6][7][8][9][10]. This may be used in the investigation structure of ferromagnetic steels [11,12], that are commonly used in the industry.…”

The article presents the possibility of using the magnetoelastic effects to monitor mechanical strain in trusses. Test stand enabling loading of the special truss structure was designed, which allowed for installation of sample members. Study was carried out on two different configurations of the truss. The first configuration consists of three separate sample members. The magnetoelastic characteristics were measured for each member separately. The second configuration consists of three measuring members combined in a single magnetic circuit. Measurements of the hysteresis loops of the sample members was carried out under varying mechanical load, which allowed to obtain magnetoelastic characteristics. The obtained results confirmed the possibility of using the magnetoelastic effects to monitor stresses in the truss structures. Streszczenie. W artykule przedstawiono możliwości wykorzystania efektu magnetosprężystego do monitorowania naprężeń mechanicznych w kratownicach. Zostało wykorzystane stanowisko badawcze umożliwiające obciążanie specjalnej konstrukcji kratownicowej, pozwalającej na montaż prętów pomiarowych. Badania przeprowadzono na dwóch różnych konfiguracjach kratownicy. W pierwszej konfiguracja są umieszczone trzy oddzielne pręty pomiarowe. Charakterystyki magnetosprężyste zostały zmierzone dla każdego pręta pomiarowego osobno. Druga konfiguracja zawiera trzy pręty pomiarowe połączone w jeden obwód magnetyczny. Pomiary pętli histerezy prętów pomiarowych przeprowadzono dla różnych obciążeń mechanicznym, co pozwoliło na uzyskanie charakterystyk magnetosprężystych. Uzyskane wyniki potwierdzają możliwość wykorzystania efektu magnetosprężystego do monitorowania naprężeń w konstrukcjach kratownicowych.(Dwie metody wykorzystania efektu magnetosprężystego do oceny stanu naprężeń mechanicznych w konstrukcjach kratownicowych).
