Abstract

The effect of alloying of Cr and Fe on the formation of the approximant phase and its micromechanical behavior in Ti—Me (Cr, Fe)—Al—Si—O alloys had been studied. It was established that the content of the approximant phase in the alloys increases substantially to 97% (at.) simultaneously alloying with Fe and Cr. Ananalysis of the experimental data revealed that the Ti60Cr20Fe10Al3Si2(SiO2)5 alloy after annealing at 800 °C corresponds to the nanocrystalline state. Full text download
