Development of advanced Fe–Al–O ODS alloynmicrostructure and properties due to heat treatment
Original language description
Fe–Al–O ODS alloy prepared via mechanical alloying was subjected to three different heat treatments. Materialnbasic state exhibited a fine-grained (300–500 nm) microstructure with fine dispersion of aluminum oxide particlesn(60% up to 20 nm). Heat treatment at 1100 °C for 3 h resulted in local grain and particles coarsening.nProlongation of the heat treatment to 24 h resulted in further grain (50 % up to 5 μm) and particle (25 % withnsize 25–40 nm) coarsening. Annealing at 1200 °C for 24 h led to a bimodal microstructure (35 % of grains withnsize 100–250 μm and 45 % of particles with size 30–60 nm) and substantial oxide particle coarsening.nMicrostructural changes resulted in tensile strength decrease and ductility increase. Tensile tests at 800 °Cnrevealed a 90% decrease of tensile strength while ductility increased 4–6 times when compared to the roomntemperature tests. The hardening ratio was below 10 % for all the alloys and both test temperatures.
