Component fluctuation and lattice distortion-controlled oxidation behavior of refractory complex concentrated alloys
Source abstract
Abstract
The influence of compositional fluctuation and lattice distortion on the oxidation behavior of Ti 2ZrTa x refractory complex concentrated alloys (RCCAs) were revealed. Chemical complexity of Ti 2ZrTa x results in the formation of various oxides, including saturated and unsaturated oxides, which reduces the protection of oxidized layer and leads to the high oxidation rate. When metastable Ti 2ZrTa x alloys were oxidated and cooled in air, spinodal decomposition occurred in the matrix. The wavelength of spinodal decomposition and lattice distortion are dependent on the stability of alloys. Component fluctuation and lattice distortion make O atoms preferentially diffuse along the Zr-enriched region.
