Abstract

The influence of hydrogen on the strength and ductility of 30KhGSA and EI659 steels in quasi-static and shock-loading tests was studied experimentally. The sensitivity of the steels to hydrogenation in air under normal pressure or in hydrogen at a pressure of 25 MPa was determined from the results of tests of as-received and pre-hydrogenated samples at a temperature of 773 K and a hydrogen pressure of 50 MPa for 24 h. It is found that EI659 steel doped with tungsten and vanadium is less sensitive to hydrogenation than 30KhGSA steel doped with manganese and chromium.

Abstract

A brief review of data for the influence of helium on the hydrogen sorption and mechanical properties of nickel and 12Kh18N10T steel is presented. When in the metallic matrix, helium considerably deteriorates the ductility of these metals. It is shown that 3He present in 12Kh18N10T steel generates high-energy hydrogen traps.

Abstract

The paper presents research results related to the impact of high-pressure hydrogen (80 MPa) and radiogenic 3He and their synergetic effect on mechanical properties and structure of CrNi40MoCuTiAl alloy within the temperature range from room temperature to 873K.The samples of three different 3He concentrations have been prepared for research: ≈ 30, ≈ 80 and ≈ 190 appm. The buildup of 3He has been fulfilled using «tritium trick» technique.The tests at room temperature have shown the increasing conventional yield strength (σ0.2) and decreasing plasticity characteristics (total elongation Δ5 and reduction of area E) depend on 3He concentration increasing. However at 873 К test temperature the alloy with the maximum 3He (≈ 190 appm) concentration turned out to be more plastic than the alloy with 3He ≈ 30 and 80 appm concentration.

Abstract

Displacement of combustion products behind the chemical-reaction front in a condensed system is shown to affect combustion-wave propagation through an inert obstacle. In the experiments, pressed specimens of a Ti+C+20%TiC mixture containing an obstacle in the form of a tantalum band 10 μm to 0.6 mm thick were used. Dependences of the delay of the combustion wave during penetration through the obstacle on the obstacle thickness were obtained for the cases of small (
