Influence of hydrogen on microstructure and mechanical properties of alloys based on Ni3Al
Original language description
The hydrogen-induced effect on mechanical properties, fracture features and on deformation structures was studied in intermetallic alloys based on Ni3Al. Four ensembles of tensile specimens were prepared: stoichiometric, stoichiometric + charged by hydrogen, doped with B and Zr and doped with B and Zr + charged by hydrogen. Hydrogen was introduced at 800°C in flowing hydrogen. The tensile tests were realised at room temperature and at strain rate of 5.8x10-5 s-1. The hydrogen effect resulted in 38 % rise of the yield stress and in 19 % decrease of tensile strength for the non-doped specimens. A similar trend of the hydrogen effect was observed for B and Zr doped alloys, the yield stress increased by 8 % and the tensile strength decreased by 26 %. The fracture features and the dislocation dissociation (resulting from SEM and TEM observations, respectively) were affected by the presence of hydrogen in non-doped and B+Zr doped alloys.
