Microstructure of TiAl-Nb alloys after thermal hydrogen processing
Original language description
Study of hydrogen effect on microstructure change after different heat treatment under argon or hydrogen was carried out. Experimental alloys Ti45Al10Nb and Ti40Al15Nb were prepared from TiNb master alloy (55/45 mass %) and pieces of elemental Al and Tiusing plasma melting. Ingots were vacuum induction remelted. Both as-cast alloys were annealed at 700°C for 8 hours under argon or hydrogen in order to compare influence of annealing atmosphere on microstructure changes. Heat treatment at 1300°C for 4 hours in flowing hydrogen followed by quenching in water from 700°C allowed to observe influence of hydrogen as phase-stabilizer in the microstructure. Based on microhardness values the influence of various parameters, such as Nb content, presence of hydrogen in the structure or thermal history of the alloys on the microstructure feature, was evaluated. The lamellar microstructure (a2 + g) was found for both alloys in as-cast condition. Hydrogen effect on increasing microhardness was obser
