Mechanical and structural properties of Ni3Al based alloys after hydrogenation
Original language description
The hydrogen effect on mechanical properties and structure features of Ni3Al based alloys was investigated. Four ensembles of tensile specimens were prepared: binary, binary hydrogen-charged, B and Zr-doped, B and Zr-doped hydrogen-charged. Hydrogenationwas carried out at 800 °C in the flow of hydrogen gas. Tensile testing was performed. The hydrogen effect resulted in 38 % rise of the yield strength on the one hand and on the other hand in 19 % decrease of tensile strength of the binary hydrogen-charged specimens. A similar tendency of the hydrogen effect on the yield strength rise was observed for doped alloys, in this case, however, only by 8 % while the tensile strength decrease was more distinct than in case of undoped specimens, namely by 26 %.Metallographic and fractographic studies as well as microanalysis and chemical analysis of selected specimens were carried out after tensile testing. The hydrogen content in tested material was assessed to be in the range from 21 to 38 pp
