| High entropy alloy as new alloy, due to its high strength, high hardness, highwear resistance, corrosion resistance, high thermal resistance, high resistance andgood electrical and magnetic properties, etc. extensively studied by scholars. Forcorrosion CrFeCoNiTixAlloy energy is relatively small.By induction melting out CrFeCoNiTixalloy, using X-ray diffraction analysis ofthe structure and composition of the alloy phase, anisotropy alloys; Alloy structureand electron density, atomic size difference and the relationship between entropyalloys; brittle larger CrFeCoNiTi1.5alloys in low returns processing, influence ofannealing temperature on the structure of the alloy; alloy surface morphology wasobserved by scanning electron microscope spectrometer comes with the distributionof the alloy elements were analyzed; observe alloy in seawater, sulfuric acid andWang water corrosion, corrosion resistance alloys studied.It was found that with increasing Ti content, CrFeCoNiTixalloy anisotropy andthen decreased; CrFeCoNiTixalloy structural change to BCC by FCC, accompaniedby HCP structure, with the Ti content increases HCP also into BCC; in when the lowtemperature heat treatment, to improve the heat treatment temperature is beneficialCrFeCoNiTi1.5in HCP structure phase precipitates; increasing Ti content, Nigradually to intergranular aggregates, Cr and Fe by the uniform distribution of theintergranular gradually to the crystal, Co and Ti in the crystal between and crystalsare relatively evenly distributed; CrFeCoNiTi1.5in the low-temperature annealingprocess, as the temperature rises Cr, Fe, Co and Ni to the distribution of crystalaggregates, Ti gradually to intergranular aggregates; CrFeCoNiTi1.0of corrosionbetter than CrFeCoNiTi0.5. |
