Study of the effect of heat treatment on the structure of surface alloys formed on cp-titanium plates by electron beam cladding in the air atmosphere
Abstract
The effect of different heat treatment on the structure of Ti-Ta-Zr layers formed by electron beam cladding in the air atmosphere on titanium substrates was investigated. It was established that annealing of surface alloys at the temperature of 900 °C promoted the formation of an equilibrium coarse-plate structure regardless of the concentration of the alloying elements. No complete annealing occurred at temperatures below 800 °C. Quenching of the layer with 26 % Ta, 15 % Zr from 900 °C made it possible to obtain a more homogeneous structure of the material. Significant changes in the morphology of alloys were also observed for layers with a lower concentration of tantalum after quenching from 600…900 °C.
